How to use Solver in Excel with examples
The tutorial explains how to add and where to find Solver in different Excel versions, from 2016 to 2003. Stepbystep examples show how to use Excel Solver to find optimal solutions for linear programming and other kinds of problems.
Everyone knows that Microsoft Excel contains a lot of useful functions and powerful tools that can save you hours of calculations. But did you know that it also has a tool that can help you find optimal solutions for decision problems?
In this tutorial, we are going to cover all essential aspects of the Excel Solver addin and provide a stepbystep guide on how to use it most effectively.
What is Excel Solver?
Excel Solver belongs to a special set of commands often referred to as Whatif Analysis Tools. It is primarily purposed for simulation and optimization of various business and engineering models.
The Excel Solver addin is especially useful for solving linear programming problems, aka linear optimization problems, and therefore is sometimes called a linear programming solver . Apart from that, it can handle smooth nonlinear and nonsmooth problems. Please see Excel Solver algorithms for more details.
How to add Solver to Excel
The Solver addin is included with all versions of Microsoft Excel beginning with 2003, but it is not enabled by default.
To add Solver to your Excel, perform the following steps:
 In Excel 2010  Excel 365, click File > Options . In Excel 2007, click the Microsoft Office button, and then click Excel Options .
To get Solver on Excel 2003 , go to the Tools menu, and click AddIns . In the AddIns available list, check the Solver Addin box, and click OK .

Where is Solver in Excel 2003?
Now that you know where to find Solver in Excel, open a new worksheet and let's get started!
How to use Solver in Excel
Before running the Excel Solver addin, formulate the model you want to solve in a worksheet. In this example, let's find a solution for the following simple optimization problem.
Problem . Supposing, you are the owner of a beauty salon and you are planning on providing a new service to your clients. For this, you need to buy a new equipment that costs $40,000, which should be paid by instalments within 12 months.
Goal : Calculate the minimal cost per service that will let you pay for the new equipment within the specified timeframe.
And now, let's see how Excel Solver can find a solution for this problem.
1. Run Excel Solver
2. define the problem.
The Solver Parameters window will open where you have to set up the 3 primary components:
 Objective cell
Variable cells
Constraints.
Exactly what does Excel Solver do with the above parameters? It finds the optimal value (maximum, minimum or specified) for the formula in the Objective cell by changing the values in the Variable cells, and subject to limitations in the Constraints cells.
The Objective cell ( Target cell in earlier Excel versions) is the cell containing a formula that represents the objective, or goal, of the problem. The objective can be to maximize, minimize, or achieve some target value.
Variable cells ( Changing cells or Adjustable cells in earlier versions) are cells that contain variable data that can be changed to achieve the objective. Excel Solver allows specifying up to 200 variable cells.
In this example, we have a couple of cells whose values can be changed:
 Projected clients per month (B4) that should be less than or equal to 50; and
 Cost per service (B5) that we want Excel Solver to calculate.
The Excel Solver Constrains are restrictions or limits of the possible solutions to the problem. To put it differently, constraints are the conditions that must be met.
To add a constraint(s), do the following:
 Click the Add button right to the " Subject to the Constraints " box.
 In the Constraint window, enter a constraint.
 Click the Add button to add the constraint to the list.
 Continue entering other constraints.
 After you have entered the final constraint, click OK to return to the main Solver Parameters window.
Excel Solver allows specifying the following relationships between the referenced cell and the constraint.
 Less than or equal to , equal to , and greater than or equal to . You set these relationships by selecting a cell in the Cell Reference box, choosing one of the following signs: <= , =, or >= , and then typing a number, cell reference / cell name, or formula in the Constraint box (please see the above screenshot).
 Integer . If the referenced cell must be an integer, select int , and the word integer will appear in the Constraint box.
 Different values . If each cell in the referenced range must contain a different value, select dif , and the word AllDifferent will appear in the Constraint box.
 Binary . If you want to limit a referenced cell either to 0 or 1, select bin , and the word binary will appear in the Constraint box.
To edit or delete an existing constraint do the following:
 In the Solver Parameters dialog box, click the constraint.
 To modify the selected constraint, click Change and make the changes you want.
 To delete the constraint, click the Delete button.
In this example, the constraints are:
 B3=40000  cost of the new equipment is $40,000.
 B4<=50  the number of projected patients per month in under 50.
3. Solve the problem
After you've configured all the parameters, click the Solve button at the bottom of the Solver Parameters window (see the screenshot above) and let the Excel Solver addin find the optimal solution for your problem.
Depending on the model complexity, computer memory and processor speed, it may take a few seconds, a few minutes, or even a few hours.
The Solver Result window will close and the solution will appear on the worksheet right away.
 If the Excel Solver has been processing a certain problem for too long, you can interrupt the process by pressing the Esc key. Excel will recalculate the worksheet with the last values found for the Variable cells.
 To get more details about the solved problem, click a report type in the Reports box, and then click OK . The report will be created on a new worksheet:
Excel Solver examples
Below you will find two more examples of using the Excel Solver addin. First, we will find a solution for a wellknown puzzle, and then solve a reallife linear programming problem.
Excel Solver example 1 (magic square)
I believe everyone is familiar with "magic square" puzzles where you have to put a set of numbers in a square so that all rows, columns and diagonals add up to a certain number.
For instance, do you know a solution for the 3x3 square containing numbers from 1 to 9 where each row, column and diagonal adds up to 15?
It's probably no big deal to solve this puzzle by trial and error, but I bet the Solver will find the solution faster. Our part of the job is to properly define the problem.
With all the formulas in place, run Solver and set up the following parameters:
 Set Objective . In this example, we don't need to set any objective, so leave this box empty.
 Variable Cells . We want to populate numbers in cells B2 to D4, so select the range B2:D4.
 $B$2:$D$4 = AllDifferent  all of the Variable cells should contain different values.
 $B$2:$D$4 = integer  all of the Variable cells should be integers.
 $B$5:$D$5 = 15  the sum of values in each column should equal 15.
 $E$2:$E$4 = 15  the sum of values in each row should equal 15.
 $B$7:$B$8 = 15  the sum of both diagonals should equal 15.
Excel Solver example 2 (linear programming problem)
This is an example of a simple transportation optimization problem with a linear objective. More complex optimization models of this kind are used by many companies to save thousands of dollars each year.
Problem : You want to minimize the cost of shipping goods from 2 different warehouses to 4 different customers. Each warehouse has a limited supply and each customer has a certain demand.
Goal : Minimize the total shipping cost, not exceeding the quantity available at each warehouse, and meeting the demand of each customer.
Source data
Formulating the model
To define our linear programming problem for the Excel Solver, let's answer the 3 main questions:
 What decisions are to be made? We want to calculate the optimal quantity of goods to deliver to each customer from each warehouse. These are Variable cells (B7:E8).
 What are the constraints? The supplies available at each warehouse (I7:I8) cannot be exceeded, and the quantity ordered by each customer (B10:E10) should be delivered. These are Constrained cells .
 What is the goal? The minimal total cost of shipping. And this is our Objective cell (C12).
To make our transportation optimization model easier to understand, create the following named ranges:
Range name  Cells  Solver parameter 
Products_shipped  B7:E8  Variable cells 
Available  I7:I8  Constraint 
Total_shipped  G7:G8  Constraint 
Ordered  B10:E10  Constraint 
Total_received  B9:E9  Constraint 
Shipping_cost  C12  Objective 
The last thing left for you to do is configure the Excel Solver parameters:
 Objective: Shipping_cost set to Min
 Variable cells: Products_shipped
 Constraints: Total_received = Ordered and Total_shipped <= Available
How to save and load Excel Solver scenarios
When solving a certain model, you may want to save your Variable cell values as a scenario that you can view or reuse later.
For example, when calculating the minimal service cost in the very first example discussed in this tutorial, you may want to try different numbers of projected clients per month and see how that affects the service cost. At that, you may want to save the most probable scenario you've already calculated and restore it at any moment.
Saving an Excel Solver scenario boils down to selecting a range of cells to save the data in. Loading a Solver model is just a matter of providing Excel with the range of cells where your model is saved. The detailed steps follow below.
Saving the model
To save the Excel Solver scenario, perform the following steps:
 Open the worksheet with the calculated model and run the Excel Solver.
 Excel will save your current model, which may look something similar to this:
Loading the saved model
When you decide to restore the saved scenario, do the following:
 In the Solver Parameters window, click the Load/Save button.
 This will open the main Excel Solver window with the parameters of the previously saved model. All you need to do is to click the Solve button to recalculate it.
Excel Solver algorithms
When defining a problem for the Excel Solver, you can choose one of the following methods in the Select a Solving Method dropdown box:
 GRG Nonlinear. Generalized Reduced Gradient Nonlinear algorithm is used for problems that are smooth nonlinear, i.e. in which at least one of the constraints is a smooth nonlinear function of the decision variables. More details can be found here .
 LP Simplex . The Simplex LP Solving method is based the Simplex algorithm created by an American mathematical scientist George Dantzig. It is used for solving so called Linear Programming problems  mathematical models whose requirements are characterized by linear relationships, i.e. consist of a single objective represented by a linear equation that must be maximized or minimized. For more information, please check out this page .
 Evolutionary . It is used for nonsmooth problems, which are the most difficult type of optimization problems to solve because some of the functions are nonsmooth or even discontinuous, and therefore it's difficult to determine the direction in which a function is increasing or decreasing. For more information, please see this page .
This is how you can use Solver in Excel to find the best solutions for your decision problems. At the end of this post, you can download the sample workbook with all the examples discussed in this tutorial and reverseengineer them for better understanding. I thank you for reading and hope to see you on our blog next week.

Define and solve a problem by using Solver
Solver is a Microsoft Excel addin program you can use for whatif analysis. Use Solver to find an optimal (maximum or minimum) value for a formula in one cell — called the objective cell — subject to constraints, or limits, on the values of other formula cells on a worksheet. Solver works with a group of cells, called decision variables or simply variable cells that are used in computing the formulas in the objective and constraint cells. Solver adjusts the values in the decision variable cells to satisfy the limits on constraint cells and produce the result you want for the objective cell.
Put simply, you can use Solver to determine the maximum or minimum value of one cell by changing other cells. For example, you can change the amount of your projected advertising budget and see the effect on your projected profit amount.
Example of a Solver evaluation
In the following example, the level of advertising in each quarter affects the number of units sold, indirectly determining the amount of sales revenue, the associated expenses, and the profit. Solver can change the quarterly budgets for advertising (decision variable cells B5:C5), up to a total budget constraint of $20,000 (cell F5), until the total profit (objective cell F7) reaches the maximum possible amount. The values in the variable cells are used to calculate the profit for each quarter, so they are related to the formula objective cell F7, =SUM (Q1 Profit:Q2 Profit).
1. Variable cells
2. Constrained cell
3. Objective cell
After Solver runs, the new values are as follows.
Define and solve a problem
Note: If the Solver command or the Analysis group is not available, you need to activate the Solver addin. See: How to activate the Solver addin.
In the Set Objective box, enter a cell reference or name for the objective cell. The objective cell must contain a formula.
Do one of the following:
If you want the value of the objective cell to be as large as possible, click Max .
If you want the value of the objective cell to be as small as possible, click Min .
If you want the objective cell to be a certain value, click Value of , and then type the value in the box.
In the By Changing Variable Cells box, enter a name or reference for each decision variable cell range. Separate the nonadjacent references with commas. The variable cells must be related directly or indirectly to the objective cell. You can specify up to 200 variable cells.
In the Subject to the Constraints box, enter any constraints that you want to apply by doing the following:
In the Solver Parameters dialog box, click Add .
In the Cell Reference box, enter the cell reference or name of the cell range for which you want to constrain the value.
Click the relationship ( <= , = , >= , int , bin , or dif ) that you want between the referenced cell and the constraint.If you click int , integer appears in the Constraint box. If you click bin , binary appears in the Constraint box. If you click dif , alldifferent appears in the Constraint box.
If you choose <=, =, or >= for the relationship in the Constraint box, type a number, a cell reference or name, or a formula.

Excel Exercises helps regular people learn Excel as quickly as possible.
Becoming the "spreadsheet wizard" of the office used to require years of industry experience and endless hours of watching excel training videos and tutorials online. excel exercises is the new method to learn excel that's faster, easier, and a lot more fun..
Trusted by users from these organizations (& many more!)
"I finished up all the lessons, they really helped me understand Excel logic better. Can't wait for more!"
"i stumbled across your website with excel exercises, and it's seriously an amazing resource [...] i seriously believe your platform proves to be one of the most efficient ways to learn excel", "when i first started the practice exercises at your site i just found it really acclerated my comprehension of excel. i started to understand it so much better than any other prior learning platform that i had visited.", a better way to learn excel skills.
Welcome to the fun, handson way to learn Excel! My name is Jake and I'm known as a spreadsheet wizard around my office, but it wasn't a fast or easy process to get here. I watched several hours worth of Excel training videos, but found I didn't really master a formula until I actually got my hands dirty and used the formula at work. It took me a few years of working in finance and consulting using Excel nearly every day to internalize all the keyboard shortcuts and functions. I started wondering why there wasn't an easier and faster way to master Excel.
Like I mentioned before, I spent hours watching Excel training videos, but they were honestly kind of boring. I'd find myself zoning out and would need to rewind and rewatch each video two or three times. And without immediately putting the techniques from the videos into practice, I'd forget the techniques right after watching the video.
Excel Practice For Real People
Practice Excel the right way  in small, bitesized, engaging lessons, rather than falling asleep reading a lengthy article or daydreaming through a long video. This is Excel practice for those who learn by doing, not by watching. There's a reason thousands of people are choosing to get their Excel practice from Excel Exercises: because it works. Each lesson is designed to keep you engaged and entertained while walking you through new concepts, so that you can't advance if you're not absorbing the information.

Imagine you want to maximize your profit by adjusting prices and costs while keeping prices and costs within specific limits. Or, you need to allocate your remaining budget across multiple projects with certain spending constraints. Excel Solver can help you achieve these goals efficiently.
Excel Solver is a powerful tool in Microsoft Excel that helps you find the best solutions by adjusting multiple inputs. Use Solver in Excel to maximize or minimize outcomes like profit, cost, or efficiency.
Key Features of Excel Solver
 Optimization : Solver helps you find the best values for your inputs to get the desired results. Increase profits, reduce costs, or meet specific targets easily.
 Multiple Variables : Adjust several inputs at once, making Solver perfect for complex problems.
 Constraints : Set limits for your inputs, such as keeping prices within a range or ensuring numbers are whole.
 GRG Nonlinear: Best for nonlinear problems, finding a local best solution.
 Simplex LP: Ideal for linear problems.
 Evolutionary: Great for complex problems, finding a global best solution.
Often our students ask: Where is Solver in Excel?
Did you know the Microsoft Solver addin is included with all versions of Excel since 2003, but it’s not enabled by default? Here’s how you can quickly activate it:
 Open Excel: Start by opening your Excel application.
 Go to File : Click on the “File” tab in the top left corner.
 Select Options : Choose “Options” from the dropdown menu.
 Choose Addins : In the Excel Options window, click on “Addins”.
 Manage Addins : At the bottom of this window, find the “Manage” box. Select “Excel Addins” and click “Go”.
 6. Enable Solver : Check the box next to “Solver Addin”.
 7. Confirm: Click “OK” to activate Solver.
Now, you can find Solver under the “Data” tab in the “Analyze” section.
How to Use Solver in Excel – Example
Goal Seek is great, but it only changes one input variable. For more complex problems with multiple variables, Solver is the tool you need.
Here’s a simple example:
You want to achieve a target income of 2,000 by adjusting the units sold and the price per unit.
 Units Sold: Input variable.
 Price per Unit : Input variable.
 Revenue : Calculated as Units Sold * Price per Unit
 Cost per unit : A fixed number.
 Total Costs : Calculated as Units Sold * Cost per Unit.
 Income : Calculated as Revenue – Total Costs.
Constraints
 Units sold must be a whole number.
 Price per unit should be between 3 and 4.
Using Solver in Excel
When you open the Solver Parameters window, you need to set up three primary components: the objective cell, variable cells, and constraints. Here’s how to do it:
Set the Objective
Objective cell: This is the cell that contains the formula you want to optimize. For example, if you want to maximize profit or minimize costs, select the cell with that calculation.
In our example, the objective cell is $B$11, which calculates the income.
 Go to the Data tab, find the Analyze section, and click Solver. Set the objective cell ($B$11) to a value of 2,000.
Select Variable Cells
These are the cells that Solver will change to achieve the objective. Highlight the cells you want to adjust.
 For our example, these are the units sold and the price per unit, so we select $B$3:$B$4 and $B$8.
Add Constraints
Constraints are the limits you set for your variable cells. Click “Add” in the Solver Parameters window to specify these limits. For our example, set the units sold to be a whole number (integer) and the price per unit to be between 3 and 4.
 Click “Add” to set limits. Specify that units sold must be an integer and the price per unit should be between 3 and 4.
 Choose Solving Method: Select the appropriate solving method (e.g., GRG Nonlinear).
Click on Solve. The Solver Results window will pop up, saying that it has found a solution. You will notice that the values of the input cells have changed but the formulas in your calculated cells have been retained. You are given the option to accept the new values by clicking on OK, or reject them by clicking on Cancel.
Excel Solver offers three methods to find the best solution for your problem. Here’s a quick overview:
GRG Nonlinear
 Best For: Nonlinear problems.
 How It Works: Finds a local optimal solution.
 Default Method: This is the most commonly used method and is set as the default.
 Best For: Linear problems.
 How It Works: Efficiently solves problems with linear relationships.
Evolutionary
 Best For: Complex and nonsmooth nonlinear problems.
 How It Works: Searches for a global optimal solution, which can take longer to run compared to GRG Nonlinear.
Solver can be a powerful tool when you need to allocate a budget among multiple projects, especially with specific constraints. Here’s an example to illustrate how to use Solver for this purpose:
You need to distribute a budget across several projects, with the following constraints:
 Extra costs should not exceed 1,000.
 Fixed costs must remain at 2,000.
 Total project cost for each project should not exceed 9,600.
Setting Up Solver
Set objective :.
 Go to the “Data” tab, find the “Analyze” section, and click on “Solver”. Set the objective cell ($B$14) to a value of 65,000.
Select Variable Cells:
Highlight the cells that Solver can change:
 Extra costs: $D$5:$D$13
 Production costs: $B$5:$B$13 (we choose Production Cost instead of Total Costs because the latter is a calculated field).
Add Constraints:
Click “Add” in the Solver Parameters window to set the following constraints:
 Extra costs ($D$5:$D$13) must be less than or equal to 1,000 ($E$18).
 Total project cost ($E$5:$E$13) must be less than or equal to 9,600 ($E$20).
Solve: Choose the appropriate solving method (e.g., GRG Nonlinear) and click “Solve”. Solver will find the best solution, adjusting the input cells within the defined constraints.
 Start Simple: Begin with straightforward scenarios and gradually add complexity.
 Experiment: Try different settings and constraints to see how they affect the outcome.

Here's how i get the bokeh photo effect using my smartphone, are gacha games worth your time 10 pros and cons.
A lot of people view Microsoft Excel as a tool that's only useful in business. Truth is, there are a lot of ways it can benefit you at home as well. The key to finding uses of Excel in daily life is picking the right formulas that solve problems.
Whether you're shopping for a new car loan, want to figure out which mutual fund investment is best for you, or if you're just trying to make sense out of your bank account, Excel is a powerful tool that can help.
We picked out 15 formulas that are simple, powerful, and help you solve complex issues.
Financial Formulas
Shopping for a new home and confused by all the mortgage lingo? Looking for a new car and getting confused by the car loan terms the salesperson keeps throwing at you?
Have no fear. Before you take out a loan, do your research with Excel by your side!
1. PMTPayment
Whenever you're comparing any loan terms and want to quickly figure out your actual monthly payment given different variations in terms, take advantage of the powerful (and simple) PMT formula.
Here's what you need to use this formula:
 The interest rate of the loan
 The term of the loan (how many payments?)
 The starting principle of the loan
 Future value, if for some reason the loan will be considered paid off before it reaches zero (optional)
 Type of loan0 if payments due at the end of each month, or 1 if they're due at the beginning (optional)
Here's a cool way to quickly compare a variety of loans to see what your payments will look like. Create an Excel sheet that lists every potential loan and all available information about them. Then, create a "Payments" column and use the PMT formula.
Just grab the lower right corner of the PMT cell you just created, and drag it down so it calculates the payment total for all the loan terms listed in the sheet. The Excel autofill feature is one feature you will use a lot with these tricks.
Now you can compare monthly payments for different kinds of loans.
(A very big thank you to Mark Jones (@redtexture on Twitter) who pointed out that for PMT and FV formulas, you've got to be very careful about using the same periodin this case using monthly payments requires dividing the interest term by 12 months)
This is why our readers are so great. Thanks for helping with this fix Mark!
2. FVFuture Value
The next formula comes in handy when you are looking to invest some money into something like a Certificate of Deposit (CD), and you want to know what it will be worth at the end of the term.
Here's what you need to know to use the FV formula :
 Number of payments (or investment term in months)
 The payment for each period (usually monthly)
 Current starting balance (optional)
So let's compare several CDs using the terms that you know from the information the banks have given you. In the example below, let's say you have a $20,000 inheritance to invest in a CD.
Interest rates are again represented in decimal format (take the interest rate the bank gave you and divide by 100). Payments are zero because CD's are typically based on a starting value and a future value paid out. Here's what the comparison looks like when you use the FV formula for every CD you're considering.
Without a doubt, the higher interest CD over a longer period of time pays out much more. The only drawback is that you can't touch any of your money for three whole years, but that's the nature of investing!
34. Logical FormulasIF and AND
Most banks these days give you the ability to download nearly a year's worth of bank transactions to a format like CSV. This is a perfect format to analyze your spending using Excel, but sometimes the data you receive from banks is very disorganized.
Using logical formulas are a great way to spot overspending.
Ideally, the bank either automatically categorizes your spending or you've set up your account so that things are placed into spending categories. For example, any restaurants we go to get labeled with the DiningOut label.
This makes it easy to use a logical formula to identify whenever we've gone out to eat and spent over $20.
To do this, just create a logical formula in a new column looking for any value where the category column is "DiningOut" and the transaction column is larger than $20
Note: The comparison below shows "<", less than, because the values in column C are all negative.
Here's what that looks like:
Using IF and AND together in one formula looks tricky, but it's actually quite simple. The IF statement will output the dollar amount (C2) if the AND statement is true, or FALSE if it isn't. The AND statement checks whether the category is "DiningOut" and the transaction is greater than $20.
There you have it! Without having to manually sift through all those transactions, you now know exactly those times when you've overspent in a certain category.
Making Sense of Lists
Lists are a big part of everyday life. If you're managing a household, you're using lists constantly. Excel has some pretty powerful tools for being productive with checklists , as well as other kinds of list formats.
56. COUNT and COUNTIF
Excel can help you quickly organize and sort values is a list. Let's take the PTC example. Here's a list of donations from community members.
We want to see how many times a person's name shows up on the list. To do this, you can combine the COUNT formula with an IF formula. First, create a column to check if the person is Michelle or not. The formula will use an IF statement to fill the cell with a "1" if this is true.
Next, create another column that counts how many times you've found Michelle Johnson on the list.
This gives you the count of every place in Column E where there's a 1 rather than a blank.
So, this is the simplest way to do this kind of thing, but it does require two steps.
68. SUMIF, COUNTIF, AVERAGEIF
If you don't mind using a slightly more advanced formula, you might consider using one of the many combined "IF" formulas like SUMIF , COUNTIF , or AVERAGEIF . These allow you to perform the formula (COUNT, SUM or AVERAGE) if the logical condition is true. Here's how it works using the above example.
This formula looks at column A, which contains all the donor names, and if the cell within the range matches the criteria in quotes, then it counts up by one. This gives you a count of all the times the donor name equals "Michelle Johnson" in a single step.
It's much faster than using two columns, but is a little complex  so use the approach that works best for your situation.
The SUMIF and AVERAGEIF formulas work the very same way, just with different mathematical results. Using SUMIF in this example would give you the total donation dollars for Michelle Johnson if you use it instead.
Another formula that you can use creatively sometimes is the LEN formula. This formula is one of many Excel text formulas that tells you how many characters are in a string of text.
One interesting way to use this in the example above would be to highlight donors who donated over $1,000 by counting the number of digits in the donation column. If the length of the number is 4 or greater, then they donated at least $1,000.
Now you can add additional formatting to make it easier on the eyes.
To do this, you need to highlight all the cells in the Donation column, select the Home tab in the menu, and click on Conditional Formatting in the toolbar. Then select Use a formula to determine which cells to format .
Set the range under Format values where this formula is true: to the column/range where all your LEN formula outputs are displayed.
In this example, if you make the condition ">3", then anything over $1,000 will receive the special formatting. Don't forget to click the Format... button and choose what kind of special formatting you want for these.
Also, a quick note. You'll notice my range is defined as "$E2:$E11", not "$E$2:$E$11". When you select the range, it defaults to the former, which won't work. You need to use relative addressing as shown in the picture above. Then, your conditional formatting will work based on the condition of the second range.
Organizing Bank and Financial Downloads
Sometimes, when you download information from businesseswhether it's your bank, or your health insurance company, the format of the incoming data doesn't always match what you need it to be.
For example, let's say that in the exported data from your bank and you're given the date in the standard format.
If you want to add a new column of your own with your own that's prefaced by the year and includes the Payee information (for your own sorting purposes), extracting pieces of information from a column is really easy.
1014. RIGHT, LEFT, TEXT, and CONCATENATE
You can pull the year out of the text in that column using the RIGHT formula.
The formula above is telling Excel to take the text in column D and extract the four characters from the right side. The CONCATENATE formula pieces together those four digits, with the Payee text from column E.
Keep in mind that if you do want to extract text from a date, you will need to convert it to text format (instead of date) using the "= TEXT (D2,"mm/dd/yyyy")" formula. Then you can use the RIGHT formula to pull out the year.
What if your information is on the left? Well, instead use the LEFT formula and you can pull text from left to right.
CONCATENATE really comes in handy when you have some text from a bunch of different columns that you want to piece together into one long string. You can find out more in our guide on how to combine Excel columns .
There are also a few ways to separate text in Excel if you want to want to learn how to fully manipulate strings.
Picking Random Names from a Hat
15. randbetween.
One last fun formula is one you may use if you have to do something like pick some names out of a hat for a Christmas party. Put that hat and those scraps of paper away and instead pull out your laptop and launch Excel!
Using the formula RANDBETWEEN, you can have Excel randomly select a number between a range of numbers you specify.
The two values you need to use are the lowest and highest numbers, which should be at the ends of the range of numbers you've applied to each person's name.
Once you hit the Enter key, the formula will randomly select one of the numbers within the range.
It's about as random and tamperproof as you can possibly get. So instead of picking a number from a hat, pick a number from Excel instead!
Using Excel for Everyday Problems
As you can see, Excel isn't just for dataanalysis gurus and business professionals. Anyone can benefit from the many formulas that you'll find tucked away in Excel . Learn these formulas and you can start solving reallife problems in Excel.
Don't stop learning Excel. There is a long list of Excel formulas and functions that you can learn to use, you might find some neat little tricks you never thought Excel could do.

 Assignment Problem
Formulate the Model  Trial and Error  Solve the Model
Use the solver in Excel to find the assignment of persons to tasks that minimizes the total cost.
Formulate the Model
The model we are going to solve looks as follows in Excel.
1. To formulate this assignment problem , answer the following three questions.
a. What are the decisions to be made? For this problem, we need Excel to find out which person to assign to which task (Yes=1, No=0). For example, if we assign Person 1 to Task 1, cell C10 equals 1. If not, cell C10 equals 0.
b. What are the constraints on these decisions? Each person can only do one task (Supply=1). Each task only needs one person (Demand=1).
c. What is the overall measure of performance for these decisions? The overall measure of performance is the total cost of the assignment, so the objective is to minimize this quantity.
2. To make the model easier to understand, create the following named ranges .
Range Name  Cells 

Cost  C4:E6 
Assignment  C10:E12 
PersonsAssigned  C14:E14 
Demand  C16:E16 
TasksAssigned  G10:G12 
Supply  I10:I12 
TotalCost  I16 
3. Insert the following functions.
Explanation: The SUM functions calculate the number of tasks assigned to a person and the number of persons assigned to a task. Total Cost equals the sumproduct of Cost and Assignment.
Trial and Error
With this formulation, it becomes easy to analyze any trial solution.
For example, if we assign Person 1 to Task 1, Person 2 to task 2 and Person 3 to Task 3, Tasks Assigned equals Supply and Persons Assigned equals Demand. This solution has a total cost of 147.
It is not necessary to use trial and error. We shall describe next how the Excel Solver can be used to quickly find the optimal solution.
Solve the Model
To find the optimal solution, execute the following steps.
1. On the Data tab, in the Analyze group, click Solver.
Note: can't find the Solver button? Click here to load the Solver addin .
Enter the solver parameters (read on). The result should be consistent with the picture below.
You have the choice of typing the range names or clicking on the cells in the spreadsheet.
2. Enter TotalCost for the Objective.
3. Click Min.
4. Enter Assignment for the Changing Variable Cells.
5. Click Add to enter the following constraint.
Note: binary variables are either 0 or 1.
6. Click Add to enter the following constraint.
7. Click Add to enter the following constraint.
8. Check 'Make Unconstrained Variables NonNegative' and select 'Simplex LP'.
9. Finally, click Solve.
The optimal solution:
Conclusion: it is optimal to assign Person 1 to task 2, Person 2 to Task 3 and Person 3 to Task 1. This solution gives the minimum cost of 129. All constraints are satisfied.

This is a curated list of errors and common problems that every newcomer in Excel is likely to face.
These errors can potentially slow or even stop your work , or simply just act as a hindrance to smooth functioning. To overcome these problems is the first step to advancing your Excel skills.
This article will illustrate the Top 20 Common Excel errors that you might face, or are currently facing and how to tackle them .
We have divided these problems into three categories for easier navigation and understanding:
Formula Issues
Visual and navigation issues, operational issues.
Let’s look at each of these errors one by one and learn how to fix errors in Excel!
1. #REF! Error
#REF! error stands of reference. Excel will display #REF! error when the cell that is referenced to in a formula does not exist or is invalid . This is usually the case when:
 Referred sheet, column, or row has been deleted
 Formula contains an incorrect or invalid cell reference
Example 1:
In the table below, you will spot multiple #REF! error within formulas used in the cell.
This has happened because you have deleted a range that contains an explicit cell reference within the formula used.
To get rid of this error message we have to select the cell(s) with this error, use the Find & Replace dialog box and do the following:
Find What: #REF!
Replace With: (Leave this blank)
Press OK and it will clear the #REF error in Excel within the formula.
Let’s look at the stepbystep tutorial below to understand how to remove #REF in Excel.
Download workbook ReplacetheREFerror2.xlsx
STEP 1: To check the cell containing the cell, simply click on the cell and press F2.
Here, since you have used an explicit cell reference and it was deleted, Excel is returning a #REF error.
STEP 2: Highlight the table containing the errors.
STEP 3: Press Ctrl + H to open the Find & Replace dialog box.
STEP 4: Under Find What, input #REF! and leave Replace as blank . This is done to replace all the #REF! error with a blank.
STEP 5: Click on Replace All.
This is how your replaced data will look like:
Let’s look at another example when this error occurs due to copypasting the formula from other cells.
In the table below, you have sales data for different customers for 4 quarters and a sum formula used to calculate the total sales. The formula used to calculate the total sales value is =SUM(B4, C4, D4, E4) .
If you try and delete Column E (Quarter 4), the sum formula will change to =SUM(B4, C4, D4,#REF!) and return an error – #REF.
This error is caused because the formula to calculate the total sales uses explicit cell reference. When one of the cell references used in the formula is deleted (here cell E4), Excel is unable to calculate the value and returns an error.
A simple fix to this problem is to use a range instead of an explicit cell reference. Let’s look at the stepbystep tutorial to learn how:
STEP 1: Use formula =SUM(B4: E4) in cell F4 and copypaste the formula below to cells F5: F11.
STEP 2: Now delete Column E to get the total sales for only 3 quarters.
If you change the formula from =SUM(B4, C4, D4, E4) to =SUM(B4: E4) , you will no longer to vulnerable to #REF in Excel. This formula recalculates the total sales value by removing the deleted cell.
Hence, it is advised to use range while writing a formula instead of an explicit cell reference.
Let’s take a look at another example when the error occurred due to VLOOKUP containing an invalid cell reference.
In the table below you have quarterly and total sales for different customers and using the VLOOKUP formula, you have tried to find out the total sales for the customer name mentioned.
The formula used to find the total sales for customers mentioned in cell H4 is =VLOOKUP(H4,$A$4:$F$11,7,0).
If you look into the formula used in detail, you will see that the value used to indicate the column index number is incorrect.
The arguments for a VLOOKUP function is:
 Lookup_value = The value you want to look up in the first column of the table.
 Table_array = The table from which you need to retrieve the data.
 Col_index_num = The column number in the table array from which matching value should be returned.
 Range_lookup = Value should be 1 if you want an approximate match or 0 if you want an exact match of the return value.
Excel is returning an error in this formula because VLOOKUP is looking to return a value from the 7th column but the reference $A$4:$F$11 contains only 6 columns.
To fix this error, use the formula =VLOOKUP(H4,$A$4:$F$11,6,0).
2. #VALUE! Error
Excel displays an #VALUE! error when the variable provided in the formula is not a supported type . This Excel error can occur because of the following reasons :
 Cell is left blank or contains hidden spaces ; or
 Cell contains text instead of the number ; or
 Date is treated as text , etc.
Download workbook ValueError.xlsx
Here, we are trying to calculate the total sales amount by adding the sales achieved in both regions on different dates.
As you can see when cell D7 adds B7 and C7, it returns #VALUE! error. This is because cell B7 contains text instead of a number .
Let’s fix this!
Change the text nil to number 0 .
You can also use the function SUM instead of using the addition operator (+). As formulas with operators will not calculate cells with tex t and instead display VALUE error.
If you use functions they will simply ignore text values and calculate everything else .
Sometimes, VALUE error will be displayed when the cell contains hidden spaces . These spaces will look like the cell is blank but in fact, it contains a space instead.
In this example, you can see even though cell B7 looks like it is a blank, value is cell D7 is displaying an error . This is because cell B7 actually contains hidden space !
There can be numerous cells that may contain hidden spaces and it may be difficult to spot and remove them.
So, follow these steps below to find extra spaces and remove them!
STEP 1: Select the range that contains hidden spaces.
STEP 2: Press Ctrl + F to open the Find & Replace dialog box and select Replace tab.
STEP 3: Type in an extra space in Find what field and keep Replace field blank .
STEP 3: Press Replace All button. This is remove all the hidden spaces in the selected cells and leave them blank .
All the errors will now disappear!
In this example, we are trying to add duration to the start day of the project in order to get the project’s end date
Here, cells C7 and C11 are displaying #VALUE! error as Excel cannot recognize the value as a date . This is because date is separated using the decimal points as delimiters .
Let’s change the delimiter from decimal point (.) to hyphen () !
STEP 1: Select the cells containing dates.
STEP 2: Press Ctrl+H to open Find & Replace dialog box.
STEP 3: Type decimal point in Find What field and hyphen in Replace With field.
STEP 4: Press Replace All button.
This will replace decimal point with hyphen. Excel will now treat them as dates and make your formula work perfectly .
3. #DIV/0 Error
This error in Excel occurs when you attempt to divide a number with zero , any value equivalent to zero, or a blank cell .
download excel workbook Diverror.xlsx
The Excel DIV 0 is a common and simple error that can easily be dealt with . To correct this error, all we have to do is make sure that the cell reference provided does not belong to an empty cell .
In the example below, the formula in column C is a simple dividing formula. But, cells B9 and B12 have blank cells respectively, and hence result from the division in column C returns the #DIV/0 Error.
Now if we simply correct our mistakes by editing the cells in column B , the errors will disappear.
In most cases, the referenced cell should actually contain the value 0 or be empty . A simple solution to this will be to use an IFERROR formula and get rid of the error message.
We can design the IFERROR formula in such a way that it either returns 0 or any value as desired if the result of the original formulas occurs to be an error .
What does it do?
It returns a value that you set if a formula has an error
Formula breakdown:
=IFERROR(Value, Value if Error)
What it means:
=IFERROR(The Formula, What do you want to show if The Formula has an error?)
If you have a calculation that results in an error like, #N/A, #VALUE!, #REF!, #DIV/0!, #NUM!, #NAME?, then you can clean it up by using the IFERROR function which allows you to replace the error it with a custom text .
In this example, cell B9 contains 0, and cell B12 is empty. The corresponding cells C7 and C12 are thus displaying #DIV error.
Let’s wrap the division formula around the IFERROR formula and see what happens.
=IFERROR(A7/B7,”“)
Here, we specified in the formula that if the value in cell C7 returns an error , it will be replaced by our custom text – hyphen () .
Apply the same formula to the rest of the cells by dragging the lower right corner downwards.
Hence as cells B9 and B12 had blank or 0 values , the corresponding cells in column C should produce an error but IFERROR changes it to display hyphen () .
4. #NULL! Error
This error occurs when the range provided in the formula is not valid and you have provided an incorrect character instead of the required character in the range.
This can be mainly due to two reasons :
 Wrong input instead of a colon (:)
 Wrong input instead of a comma (,)
download excel workbook Nullerror.xlsx
Sometimes in a formula, where there is supposed to be “:”(colon), you might have entered space . This can be the result of the error that we are getting as shown below.
In the formula bar, we can see that instead of =SUM(A7:A13), it is entered as =SUM(A7 A13) , which is the cause of the error.
So to correct this, we have to replace that space with a colon(:) .
Like so! As the typo has been corrected, the error has been removed and the formula is returning the correct value.
Sometimes in a formula, where there is supposed to be “,”(comma), you might have entered space .
In this example, we are trying to calculate the average speed in cell B11 based on the 3 entries mentioned in rows 7, 8, and 9. The formula used is:
=AVERAGE(C7,C8 C9)
This can lead to an error that we are getting as shown below:
Here, instead of =AVERAGE(C7,C8 C9) you should enter the formula as =AVERAGE(C7,C8,C9) .
There should have been a comma between C8 and C9 but instead, there has been a typing error and instead of the comma, space was inserted .
Simply removing the space and adding the comma rectifies this error.
5. #SPILL! Error
There are various formulas in Excel that populate results in multiple cells . It is termed as actually spilling the data into the neighboring cells .
The different scenarios when you can encounter this error are:
 Spill range isn’t blank
 Spill range contains merged cell
 Spill range is too big
 Spill range in a table
Excel is unable to fix these errors and display the output. Since the formula cannot populate all the cells it is supposed to, the first cell where the formula is entered shows the #SPILL! Error.
download excel workbook SPILLerror.xlsx
Example 1: Spill range isn’t blank
You want to find a unique list of customer names stated in column A using the UNIQUE function in Excel. But, Excel returns a #SPILL! error instead.
This is because the output range already contains data and Excel cannot overwrite it and populate the desired result.
Simply, clear any contents from the output range and you are good to go!
The spill error can have multiple causes. To understand the root of this problem, click on the small yellow! warning sign next to the error. It shows the cause of the problem .
Most commonly it is caused because there is a cell containing some value , but it needs to be populated by the formula. Removing the value in all such cells will remove the “blockage” and, in turn, the error.
There can be times when you get the SPILL error but you are unable to spot the cell that contains unwanted data .
Click on Select Obstructing Cells and it will take you to the cell that is creating the problem.
This is useful when you have hidden spaces and you are unable to find them.
Example 2: Spill range contains merged cells
SPILL error can also occur when the result range contains the merged cells .
In this example, you can see the spill range i.e. B7:B15 is empty but still, Excel returns #SPILL error .
To be sure of the reason , let’s click on the yellow warning sign and see what it says – Spill range has merged cell.
Now, click on Select Obstructing Cells and it will take you there.
Go to Home > Merge & Center to unmerge the cells .
The result is now visible and the error disappears!
Example 3: Spill range is too big
This error occurs when the output range is too big and the result goes beyond the boundary in Excel . There isn’t enough space to display the result.
In this example, we are trying to calculate the discount given to the customers based on the sales amount . Column C is used to get 5% of the sales amount.
As you can see, Excel is again and producing a SPILL error and this time it is because the range is too big .
Here, Excel is trying to multiply each cell in Column B by 5% and produce a million results . It will spill the result in Column C starting from cell C7 but it will reach the end of Excel.
Hence, the error!
To solve this, simply replace the column with the relevant range and copy the formula to the output range.
Example 4: Spill range in a table
Excel tables do not support spilled array formulas . If you try to insert an array formula in an Excel table, it will return a #SPILL error.
In this example, we are trying to sort the amount mentioned in Column A in ascending order using the SORT function. It will return a dynamic array as a result in column B.
Unfortunately, we are getting a #SPILL Excel error. This is because range A7:B15 is in fact saved as a table in Excel and dynamic functions do not work within Excel tables.
We can easily convert it into a range for our SORT function to work properly.
To do so: Right Click on any cell in the Table range > Select Table > Select Convert to Range .
This will convert the table to range and now all array functions will work perfectly as shown below!
6. #NAME? Error
The #NAME? Error is a fairly common one that even seasoned Excel professionals can face. It occurs when there:
 Spelling error in Formula name
 Spelling error in Cell Range
 Spelling error in Named Range
 Text entered without quotes
download excel workbook Nameerror.xlsx
Example 1: Formula Name
When entering the name of the formula if the name is misspelled , then that can lead to the occurrence of this error.
In the above example, you can see that instead of writing =LEN(A7), we have typed =lan(A7) . There is an error in the formula name, leading to the problem.
Now you can see, simply correcting the name removes the error displayed .
The best way to not get #NAME excel error is to choose the formula in the dropdown list while typing the name of the formula. This makes sure that the formula name is not misspelled.
Example 2 Cell/Range name
When entering a formula that references a certain cell or range , misspelling the name of the cell or range can lead to this error.
Here we can see that the name of the cell is misspelled . Instead of =LEN(A7), it is typed as =LEN(AA) .
To rectify this, simply type in the correct cell name .
A better way of avoiding the error is to select the cell when referencing in the formula. This will lead to always entering the correct cell name.
NAME error in Excel can occur when entering a range . Check and correct the range name or select the entire range when entering the formula to rectify the error and prevent it.
Example 3 Named range
There can be particularly important ranges in your workbook that you have assigned a name to. When referencing this range in a formula, misspelling it can lead to the #NAME error in Excel .
Here we can see that the range referenced to in the formula is spelled agee when the correct name is Age .
Correcting the name of the range or simply selecting the range when referencing it in the formula will correct this error .
Example 4 Text without quotes
Wherever a text is entered into a formula , it should be entered in quotes . When a text value is not confined between quotes , Excel reads it as either a formula or a named range /table.
If there is no formula or named range in your workbook that matches the text written in the formula, Excel will return the #NAME? Error.
Here we can see the text entered in the formula is not in quotes and hence Excel is returning it as an error.
Now that the text is written in quotes , Excel is returning the correct value of the formula.
7. #NUM! Error
Excel shows the #NUM! Error when values in formulas are invalid . It basically means that the calculation cannot be performed due to limitations or errors .
This can be due to the fact that the number is too big or small, impossible calculations , or when the data type is not supported in the argument.
download excel workbook Numerror.xlsx
Example 1 – Number size
Excel has a limitation to the size of the number that it can display. If you enter a number is too large or too small ,you will get Excel #NUM Error .
As you can see, in cell C7 we are trying to multiply 5 by itself 500 times . The result will be a really large number that Excel is unable to display. Hence. it returns NUM Excel.
In cell C10, we are trying to divide 1 by 10^750 . Since this will be a very small number Excel cannot perform calculations and hence returns #NUM error.
Excel is not able to show these values because of its inherent limitations. As shown, other smaller values are calculated and shown in C8 and C9.
Example 2 – Impossible calculations
Excel returns the #NUM! Error when it is faced with a calculation that is impossible to do.
As you can see, the square root or log of the positive numbers has results but the square root or log of the negative numbers is impossible to calculate .
In this example, we are trying to find the square root of 3 .
Since we are trying to calculate the square root of a negative number, we will get #NUM error in Excel. In this particular case, you can rectify this issue by taking the absolute value of the number.
ABS function returns the absolute value of a number . It converts negative numbers to positive numbers and keeps the positive numbers unaffected.
Including the ABS function into the formula uses the absolute value of the number in column A, so now Excel can calculate the number and return a valid answer.
Example 3 – IRR function not working
Excel might show the #NUM! error when using IRR function because of either one of the two reasons:
 Cash flow does not contain at least one negative and one positive value .
 Formula can’t find a result .
In this example, Excel results a #NUM error instead of proving a value .
This is because the cash flows provided in the range (B7:B15) are positive and IRR requires at least one negative value as the initial cost of business.
Initial payments are provided as negative value indicating outflow of cash and income payments are represented by positive values. Once you have incorporated this, the function will provide the correct result!
IRR function can also display #NUM! error when the function iterates and can’t find a result after several tries .
To overcome this, you can increase the maximum number of iterations that Excel performs to get a result.
To increase the number of iterations:
STEP 1: Go to File > Options > Formulas to arrive at the window below
STEP 2: Under the Calculation options group, check the Enable iterative calculation box.
STEP 3: In the Maximum Iterations box , type the number of times you want Excel to recalculate .
The higher the number of iterations, the more time Excel needs to calculate a worksheet. Increasing this can help give a result to your calculation.
STEP 4: In the Maximum Change box, enter the amount of deviation that you are willing to accept between the calculation results.
The smaller the number, the more accurate the result. Increasing this can help give an approximate answer to your calculations.
8. Excel #### error
Sometimes in Excel, especially when you open a file on which you have worked before , there may be some cells that are filled with “#” signs.
Excel #### error is a very simple but common issue that can easily be solved. There are three simple ways to tackle this problem.
download excel workbook HashError.xlsx
Taking your cursor to the divider between two column heads, the cursor will change into a dragger . Dragging the column head divider will change the width of the column.
Now you can increase the width to fit all the characters of the cell, or to any width that you want.
Simply doubleclicking on the rightmost edge of the column head, that contains the cell filled with # marks, will autofit the column so that it perfectly adjusts and shows all values in cells.
It will adjust to the length of the longest cell in the column.
Upon applying the above steps, your values will then be visible as shown.
Another way to overcome this problem is autoshrinking text to fit in the column width. To accomplish this, follow the steps mentioned below:
STEP 1: Select the column that shows #### error.
STEP 2: Click on the Home Tab.
STEP 3 : Click on expand icon at the bottom right corner of the Alignment group.
STEP 4: Check the Shrink to fit box in the Format Cells dialog box.
Upon applying the steps, the size of the text will be reduced to fit in the column width and it will look like this:
9. Worksheet Tabs not Visible
A common issue faced while operating on Excel is that your worksheet tabs ( shown at the bottom left) are not visible to you .
This is a simple settings problem that can be easily undone.
download excel workbook Worksheettabs.xlsx
Ever encountered this situation where you open your workbook and said “Where are my worksheet tabs ??”.
A common issue faced while operating on Excel is that all the worksheet tabs, which are shown at the bottom left of the window, are not visible to you .
Just follow the steps below to learn how to display the missing worksheet tabs:
STEP 1: Go to Files
STEP 2: Click on Options
STEP 3: Click on Advanced
STEP 4: Under the Display options for this workbook, check Show sheet tabs .
Now your sheet tabs will be available ! Now you can easily navigate through the entire workbook , and work on all sheets.
This is what to do when worksheet tabs go missing and you are unable to switch between different tabs!
It can also be that some of your worksheets might be hidden , hence you will not be able to see them in the worksheet’s tab.
Here, we actually have two worksheets, but one of them is hidden .
To show the worksheet tabs:
STEP 1: Rightclick on any visible tab and select Unhide.
STEP 2: Select the tabs you want to unhide and press on OK .
Now both the worksheets will be visible to you on the worksheet’s tab.
10. Break Line displayed on the Worksheet
While working on Excel, sometimes you may see solid or dashed break lines added and the worksheet is divided into multiples pages .
The solid lines are manually inserted ones whereas the dashed line is automatically generated .
These are basically page breaks inserted in Excel for printing purposes ! They may be useful when you are trying to print a document but other times are just visually distracting .
You may want to remove these lines before presenting your worksheet to someone!
In this article, we will cover the different ways to remove lines from the worksheet:
Solid Page Break Line
Dotted Page Break Line
download excel workbook BreakLinesonWorksheet.xlsx
In this screenshot, we have two solid lines inserted in the worksheet.
These are manually added page breaks and can easily be removed by following the stepbystep tutorial below:
STEP 1: Select the cell just below the page break line.
STEP 2: Go to the Page Layout tab.
STEP 3: Click on Breaks in the Page Setup group.
STEP 4: Click on Remove Page Break .
This will remove the page break between row 9 and row 10!
Now, follow the same steps to remove the solid line between rows 15 and 16.
When you select the Page Break Preview in Excel, the dotted and solid lines dividing the worksheet into different pages become visible.
Now when you go to View > Normal , the page preview is returned to normal but the lines still visible.
To remove the solid lines, follow the steps mentioned below. But, this will not remove the dashed lines.
To remove the dashed line, follow the steps below:
STEP 1: Select the File tab.
STEP 2: Click Options from the menu on the left side
STEP 3: In the dialog box, click on Advanced from the left panel
STEP 4: Under display options for this worksheet, uncheck Show Page Breaks .
This will remove the dashed lines from the worksheet as well!
11. Clicking Enter key goes to the cell underneath
In general, when you press enter in Excel it solidifies the work done in a cell but it automatically takes you to the cell below the one you were working on . If this is a hindrance to you, you can easily change it.
To alter the direction in which Excel files after pressing enter, follow these steps:
 Click on the File tab on the ribbon above
 Click Options from the menu on the left side
 In the dialog box, click on Advanced from the left panel
 Under Editing Option, Select After Pressing Enter Move Selection, and from the dropdown menu the choose the direction in which you want Excel to move.
Now Excel will move in the direction you want after pressing enter. Now you try it!
12. Show column headers on each page when printing
If you have a large data file with headers on the top , you can freeze the columns to easily view the entire table without losing sight of the headers.
But the freeze feature will not be applied when you try to print the file.
To print Excel header row on every page , you can try one of the following methods as per your requirement:
 Repeat row on every page
 Repeat column on every page
 Print row numbers and column letters
download excel workbook PrintRowandColumnHeaders.xlsx
Example 1: Repeat row on every page
If you have a large worksheet that spans over multiple pages, you can easily print the first row of the data as headers in Excel on every page .
Follow the steps below to print a row of every page:
STEP 1: Go to Page Layout tab > Select Print Tiles
STEP 2: In the Page Setup dialog box, select Sheet .
STEP 3: Select the collapse dialog box and pick the row you wish to repeat.
STEP 4: Click OK .
STEP 5: Press Ctrl + P to open Print Preview.
As you can see we are on page 5 but the 1st row is still visible!
Example 2: Repeat Column on every page
When your Excel worksheet has multiple columns and is spread across several pages, you can fix the first column.
Follow the steps below to fix the first column when printing:
STEP 1: Go to Page Layout > Select Print Tiles
STEP 3: Select the collapse dialog box and pick the column you wish to repeat.
STEP 4: Click OK
And it’s done! Column A is still visible when you go to page 2.
Example 3: Print row numbers and column letters
Excel denotes the worksheet’s columns as letters (A, B, C, etc) and rows as numbers (1, 2, 3, etc). But when you try to print your worksheet, it is not visible at all.
You can easily print numbers and column letters by following the steps below:
STEP 3: Check Row and column headings
STEP 5: Press Ctrl + P to view Print Preview.
The row numbers and column letters will be displayed in the print preview section!
13. Not using Quotation Marks for Text in Formulas
When writing formulas, Excel will identify a text only if it’s written within quotation marks . Excel e xtracts anything written within the quotation mark as text and discards the quotation mark.
Let’s use a formula to use to help better understand the use of quotation marks while writing a formula!
Download workbook QuotationMark.xlsx
In this example, we have tried to insert text like “Email ID of” and ” is” but Excel is returning an error . This is simply because Excel will not consider text if it is not provided within quotation marks in a formula.
Now, put them within quotes and try using this formula again.
And Voila, the error is resolved and we can now insert custom text within the formula easily.
14. How to Use Numbers as Column Headings
You may have faced a situation when you need to use numbers as column headings in the table . But, when you put in digits as heading, Excel will treat it as a number and not text .
As a result, when using auto sum or other similar features the heading will also be included with other values.
Download workbook NumberasColumnHeader.xlsx
This is not the result you were expecting ! Let’s fix it by forcing Excel to consider the number as text.
To do that, simply add a ‘ symbol in front of the number and it will be treated as text.
See, it is that simple! Try it now!
15. Unable to Directly Edit the Cell
If you are unable to edit data entered in your Excel worksheet and you are not sure how to fix it, you have come to the right place. There are several ways in which you can easily enable editing cells and learn how to edit cells in Excel.
 Excel file is readonly
 Excel worksheet is locked
 Editing in cell disabled in Excel
Example 1: Excel file is readonly
You may not be able to edit any cell in Excel because the Excel worksheet has been saved as readonly . This will force Excel to keep the worksheet in view mode and you can make no changes in the file.
To fix this, simply press the Enable Editing button on the top of the Excel worksheet.
On you press that button, you can easily edit any cell in Excel.
Example 2: Excel worksheet is locked
Another reason why you may not be able to edit cells is that your Excel worksheet has been locked . You have to unprotect your worksheet first and then you can make changes in your file.
To make changes in Excel, follow the steps below:
STEP 1: Go to the Review tab
STEP 2: Click on Unprotect Sheet
STEP 3: Enter the password in the unprotect sheet dialog box and click OK .
The password for this worksheet is “myexcelonline”.
This will unprotect the sheet and you will be able to make the edits you want.
Can’t remember the password that you had used to lock your Excel file? Click here to learn how to unprotect active worksheets using macros in Excel.
Example 3: Editing in cell disabled in Excel
You might not be able to directly edit the contents of a cell by pressing the F2 key.
This might be because it has been disabled in Excel. You can easily enable or disable this function by following the steps below:
STEP 1: Click on the File tab
STEP 4: Under Editing option, check Allow editing directly in cells. Click OK at the bottom.
That’s it! Now you can enable the editing cell feature in Excel. To disable Edit mode, clear the Allow editing directly in cells check box.
16. Unable to use the Fill Handle
Excel has many tools that can automate your work and make it much easier and faster. One of these essential tools is the fill handle . It helps fill in a value in the adjoining cells in sequential order of data.
If you are unable to use this feature , it may have been disabled or the filled values are not as per your pattern:
 Fill Handle Excel – not visible
 Not selecting all values
 Auto Fill options
Download workbook Fillhandle.xlsx
Example 1: Fill Handle not visible
If you are unable to use this function , you can simply fix it using the steps below:
STEP 3: In the Advanced category, under Editing options, select the Enable fill handle and cell draganddrop check box.
Once you have enabled this, you can easily use Excel Fill handle feature!
Example 2: Not selecting all values
It can even be that you have not selected the entire range that has your sequential values . Just selecting the last cell will fill only that value in the cells where you drag the fill handle in Excel.
For example, if we drag the fill handle after only selecting cell B8, the entire range is filled only with the value “1002”.
Selecting the entire range and then using the fill handle will fill the new cells in sequential order .
Selecting B7 and B8 will help Excel recognize the pattern and correctly fill the subsequent cells.
Example 3: Auto Fill options
Suppose you have entered the date and you want to use the fill handle to get only weekdays . If you use the fill handle like before , it will just add the next dates in adjacent cells .
You can use the AutoFill option to get dates that are only falling on weekdays!
STEP 1: Select the entered values.
STEP 2: Go to the bottom right of your selection , you can drag the fill handle to fill dates below.
This will fill the dates one after the other!
STEP 3: Click on the Fill Handle button at the bottom right.
STEP 4: Select Fill Weekdays .
This will just include the weekdays and ignore the weekends like 4Jan20 and 5Jan20.
You can use other options as well like Fill Formatting only, Fill Months, Flash Fill, etc.
17. Not able to understand the inner workings of a formula
Excel provides a lot of functions at your disposal for efficient working and data management. Formulas can be used widely in Excel to overcome or calculate all sorts of different informational data.
But these formulas can be tough to decipher at first, especially the working of a formula. Here is how you can better understand a formula:
When you enter a formula in the cell, you can press Ctrl+A to enter the function arguments window. Thi s shows a detailed explanation of each segment of the formula so that you know which data to feed in which segment and get accurate results.
To better understand this, let us take the example using the VLOOKUP formula. Here, we need to extract the salary of Rachael in cell D15 .
download excel workbook UnderstandExcelFormula.xlsx
Let’s open the arguments wizard for the VLOOKUP formula.
STEP 1: Enter the VLOOKUP function: =VLOOKUP(
STEP 2: Press Ctrl+A or click on the fx button in the formula bar to open the arguments wizard window.
This is how the formula wizard looks like.
It shows all the arguments in sequential order. It then explains the use of the function and the details of the argument selected.
STEP 3: Select the first argument i.e. Lookup_value . Here, cell C15 contains the name, Rachael.
You can also see the description of the first argument is written at the bottom of the dialog box.
STEP 4: Select the second argument i.e. Table_array and select the table range from where you can search i.e. A7:C13 .
STEP 5: Select the third argument i.e. col_index_num and enter the column number from which to extract the data. In this example, it should be 3.
STEP 6: Lastly, select the fourth argument i.e. range_lookup . Since we want an exact match type FALSE or 0 .
After entering the details, the wizard would look like below. It would even show a preview of the argument values and the answer below it if the inputs were correct.
STEP 7: Press OK .
The formula will be entered in cell D15 and it will show the result, i.e., the salary of Rachael – $16,540 .
Ctrl+A opens the Function Arguments window immediately after typing the name of the function.
Now that you can easily understand each formula, have fun working on Excel!
18. Cells showing formulas instead of calculated values
While working on an Excel worksheet with a lot of formulas in it, it can become challenging to keep track of all your formulas .
It may happen that the formulas entered in each cell is displayed on the worksheet instead of the value/result .
You can easily reverse this and display the result instead of formula. Let’s see how it can be done!
download excel workbook ShowingFormula.xlsx
Ctrl + ` is the shortcut for the formula view, pressing it can change it back to normal view and show your calculated values.
Now you have your cells showing calculated values instead of formulas applied. Try it yourself!
19. Formula does not update when value changes
Excel provides dynamic formulas that update their calculated value as soon as the source data is altered.
An issue faced by people can be that the cells are not updating automatically ,i.e, they are showing the old values even when the dependent cell’s values have been changed. Here is how you fix this issue.
The issue that you are facing is most likely caused by an accidental change in the calculation setting from Automatic to Manual . Steps to change this are:
Go to Formula Tab > Calculation Options > Automatic .
Now your formulas will be getting updated which changes in the source data. Now you try it!
20. Formula not working due to text format in cells
Sometimes even when have entered a number in the cell, it is stored as text and thus produce error while computing in Excel.
download excel workbook Formulanotworking.xlsx
In this example, cell F7 uses sum function to calculate the total amount for all 4 quarters. Even though there are figures in range B7 to E7 the calculated amount in cell F7 is 0 .
This is because each of these number are actually stored as text .
Select the cells that are the source for the formula calculation. Click on the yellow triage icon and select Convert to text.
This will convert the text to number and now the calculated amount will also display the correct value!
It is that simple! Now you try it!
This completes our tutorial on the Top 20 common errors like REF error, NUM error, Excel #### error, etc. that we can encounter while working on Excel .
Now that these common issues are out of your way , we hope that your Excel operations have improved .

Excel Solver Example problems with variables or constraints
Excel users have applied long and successfully this program to solve various types of tasks in different areas.
Excel is the most popular program in every office in the world. Its facilities allow you to quickly find effective solutions in a wide range of activities. The program is capable for solving various kinds of tasks: financial, economic, mathematical, logical, optimization and many others. For clarity we will see each of the described tasks with solving in Excel and consider it with an examples.
Solving tasks in data optimization problems
Optimization models are applied in the economic and technical sphere. Their goal is to choose a balanced solution and optimal in specific conditions (the amount of sales to receive a certain revenue, the best bill of fare, the quantity of flights, etc.).
The following commands are used to solve optimization problems in Excel:
 The Script Manager (“DATA” "Whatif Analysis"  “Scenario Manager”) analyzes several variants of the original values, creates and evaluates sets of scenarios.
 Selection of parameters (“DATA” "Whatif Analysis"  "Goal Seek") helps to find the values that will ensure the desired result.
 Solution search (Microsoft Excel addin, "DATA"  "Solver") calculates the optimal value taking into account variables and constraints. Go to the link and find out how to plug in the "Solver" setting.
The command "Parameter Selection" is using to solve the simplest tasks. You use "Scenario Manager" for the most complex tasks. Let’s consider an example of solving an optimization problem using the "Solver" addon.
Condition. The company produces several brands of yogurt. Let’s call them "1", "2" and "3". The enterprise receives 200 rubles having sold 100 jars of yoghurt "1". Brand "2" brought 250 rubles. "3"  300 rubles. The sales are wellestablished, but the amount of available raw materials is limited. You need to find what kind of yogurt and how much you need to do to get the maximum revenue from sales.
Known data (including the rate of consumption of raw materials) will be listed in the table:
We will compile a working table based on these data:
 We still do not know the number of products. These are variables.
 The following formulas are written in the column "Profit": C11:= 200*B11, C12:= 250*В12, C13:= 300*В13, C14: =SUM(C11:C13).
 The consumption of raw materials is limited (these are restrictions). The following formulas are added to the cells: milk A18: kefir B18: egg C18: sugar D18: That is, we have multiplied the consumption rate by the quantity.
 The goal is to find the maximum possible profit. This is C14 cell.
Activate the "Solver" command and enter the parameters.
The program issues its decision after clicking the "Solve" button.
The best option is to concentrate on the making yogurt "3" and "1". Kefir "2" is not worth producing.
Solving financial tasks in Excel
Most often financial functions are used for this purpose. Let's consider an example.
Condition. Let’s calculate how much to deposit, so that in four years 400,000 rubles will be formed. The interest rate is 20% per annum. Interest is accrued on a quarterly basis.
Let’s make a table with initial data:
Since the interest rate does not change during the whole period, we use the function of the =PV (Rate, Nper, Pmt, Fv, Type) to cell B7.
Filling in the arguments:
 Rate – Interest rate is 20%/4 because Interest is accrued on a quarterly basis.
 Nper – Total number of periods is 4*4 (total term of deposit*number of accruing periods per year).
 Pmt – Recurring payments is 0. We do not write anything. The deposit will not be replenished.
 Fv – Future Value is the amount of money we want to receive at the end of the deposit period.
The investor needs to deposit this money so the result is a negative number.
We use the formula To verify the correctness of the solution: PV = Fv/(1+Rate)*Nper. We substitute the values: PV=400 000 / (1 + 0.05) 16 = 183245.
Solving the econometric tasks in Excel
Mathematical and statistical methods and models are used to establish quantitative and qualitative interrelations.
There are two ranges with values:
The values of X will play the role of a factor characteristic, Y is the resultant one. The task is to find the correlation coefficient.
The function CORREL (array 1, array 2) is provided to solve this task.
Solving the logic tasks in Excel
The table processor has builtin logic functions. Any of them must contain at least one comparison operator which will determine the relation between the elements (=,>, <,> =, <=). The result of the logical expression is a Boolean value of TRUE or a Boolean value FALSE.
Task for example. The students passed the test. Each of them received a grade. The test is handed over if there are more than 4 points. If less it’s not handed over.
 Put the cursor in C1 cell. Press the function icon. Choose "IF".
 Fill in the arguments. The logical expression is B1> = 4. This is the condition under which the logical value is TRUE.
 If TRUE  "Passed the test". FALSE  "Did not pass the test".
Solving the mathematical challenges in Excel
Using the program arsenal, you can solve not only the simplest mathematical problems, but more complex (operations with functions, matrices, linear equations, etc.).
The condition for the training task. Find the inverse matrix B for the matrix A.
 We make a table with the values of matrix A.
 We highlight on the same sheet the area for the inverse matrix.
 Go to "FORMULAS". Category  "Math and Trig". Type  "MINVERSE".
 In the “Array” argument field enter the range of the matrix A.
 Press Shift + Ctrl + Enter at the same time because this is an obligatorily for entering arrays.

which of the following statements about exception handling is correct? group of answer choices statements that may cause an exception should be placed within a catch block. the main method of a java program will handle any error encountered in the program. statements that may cause an exception should be placed within a throws block. statements that may cause an exception should be placed within a try block.
The correct statement about exception handling is "Statements that may cause an exception should be placed within a try block."
In Java, exception handling is a mechanism used to handle runtime errors and unexpected conditions that may occur during program execution. When an exception occurs, the Java Virtual Machine (JVM) creates an exception object and throws it to the method that called the offending method. The program then attempts to find a suitable exception handler to catch the exception and handle it appropriately.
The trycatch block is the fundamental structure used in Java for exception handling. Statements that may cause an exception are placed within a try block. If an exception occurs within the try block, it is caught by a matching catch block, which contains code to handle the exception. Multiple catch blocks can be used to handle different types of exceptions that may be thrown within the try block.

which of the following parallel computing solutions would minimize the amount of time it takes to execute all four processes?
Parallel computing involves dividing a task into smaller subtasks that can be processed simultaneously on multiple processors, thus reducing the overall execution time. To minimize the time it takes to execute all four processes, we need to choose a parallel computing solution that maximizes parallelism and minimizes communication overhead.
One solution that can achieve this is task parallelism, where each process is assigned to a separate processor and runs independently of the others. This approach minimizes communication overhead and maximizes parallelism, allowing all processes to be executed simultaneously .
Another solution is data parallelism, where the data is divided into smaller chunks and each processor performs the same operation on its assigned data. This approach is efficient when the same operation needs to be performed on a large dataset.
In summary, to minimize the amount of time it takes to execute all four processes , we should choose a parallel computing solution that maximizes parallelism and minimizes communication overhead. Task parallelism and data parallelism are two solutions that can achieve this goal.

70. The best time to introduce security into an application is: a. Implementation b. Design c. Development d. Testing
The best time to introduce security into an application is during the design phase. By incorporating security measures into the design, potential vulnerabilities can be identified and addressed before implementation and development even begin. This is important because once implementation and development are underway, making significant changes to the design can be costly and timeconsuming.
During the design phase, security considerations such as authentication, authorization, encryption, and input validation can be integrated into the application architecture. This approach ensures that security is built into the application from the ground up and is an integral part of the application's functionality.While security testing is also important, it should not be relied upon as the sole means of identifying and addressing security vulnerabilities. By incorporating security into the design phase, developers can proactively address potential security issues before they become a problem, resulting in a more secure and reliable application .

Shifting a positive integer left by i bits gives the same result as multiplying the same integer by 2 i . N×2 i =N< . N÷2 i =N>>i Given an integer N stored at memory address 5000 , write a program that stores the result of N×8 at memory address 5004 and the result of N/16 at memory address 5008. Use the ' + ' button under the Memory display to initialize the memory at address 5000. Ex: If the content at memory address 5000 is initialized in the simulator as 64, the data memory will contain: Note: Shiftright performs an integer division; therefore, digits after the decimal point are ignored.
The task is to write a program that performs two operations on a positive integer N stored at memory address 5000. The first operation is to shift N left by i bits, which is equivalent to multiplying N by 2 i , and store the result at memory address 5004. The second operation is to shift N right by i bits, which is equivalent to dividing N by 2 i , and store the result at memory address 5008. To perform the first operation, we need to shift N left by 3 bits since we want to multiply N by 8, which is equivalent to 2 3 . This can be done using the left shift operator << in C. Therefore, we can write N<<3 to shift N left by 3 bits. To perform the second operation, we need to shift N right by 4 bits since we want to divide N by 16, which is equivalent to 2 4 . This can be done using the right shift operator >> in C. Therefore, we can write N>>4 to shift N right by 4 bits. We can then assign the results of these operations to the memory addresses 5004 and 5008 using the assignment operator = in C. Therefore, we can write *(int*)5004 = N<<3; and *(int*)5008 = N>>4; to store the results of N×8 and N/16 respectively at the required memory addresses. The program to perform the required operations on the positive integer N stored at memory address 5000 has been explained. The left shift and right shift operators in C have been used to shift N left and right by the required number of bits . The results of these operations have been assigned to the memory addresses 5004 and 5008 using the assignment operator in C.

Explain the concept of a CPUI/O burst cycle.
The concept of a CPUI/O burst cycle is a fundamental aspect of computer processing. It refers to the alternating phases of activity that occur when a program is executing on a computer's central processing unit (CPU). During these cycles, the CPU switches between periods of intense computation, known as CPU bursts, and periods of relatively little activity, known as I/O bursts. In a typical CPUI/O burst cycle, the CPU receives a task from a program and executes it during a CPU burst. This may involve performing complex calculations, accessing memory, and making decisions based on input data. Once the CPU has completed its work, it enters an I/O burst, during which it waits for input or output operations to complete. This could include reading or writing data to a disk drive, waiting for user input, or communicating with other devices on a network. The length of these bursts can vary greatly depending on the type of program being executed, the complexity of the task, and the resources available to the computer . In some cases, a program may consist primarily of CPU bursts with very short I/O bursts, while in other cases the opposite may be true. Understanding the CPUI/O burst cycle is crucial for optimizing computer performance and ensuring efficient use of system resources. By analyzing the behavior of programs and identifying patterns in their CPU and I/O activity, developers can design more effective algorithms and optimize system configurations to achieve maximum performance.

What happened at Possum Trot? Remarkable story shows how we can solve America's problems.
In possum trot, texas, a single church changed the lives of dozens of children in foster care..
We’re looking for the wrong solutions to America’s biggest problems. It’s true of poverty, homelessness, mental health, addiction and so much more. Given the scale of these challenges, we tend to assume they need even bigger answers − massive programs and taxpayer support. But after decades of taking that approach, America’s problems have gotten worse.
What if the solutions are bigger and smaller than most people think?
What happened at Possum Trot
That’s the message of “ Sound of Hope: The Story of Possum Trot ,” a movie released this week. Named after a town in East Texas and based on a true story, it follows the story of dozens of local children who were taken from their families and put in foster care. Their lives were hard, and foster care made them harder. The kids were seemingly destined for a life of violence, jail, addiction, poverty and, in many cases, death.
But the town didn’t let that happen. A local pastor, Bishop W.C. Martin , and his wife, Donna Martin , adopted two of the kids, then called on their friends and fellow parishioners to step up.
All told, 22 families adopted 77 of the hardesttoplace children in the local foster system.
That was nearly three decades ago. While many of the former foster children are still dealing with the trauma of being taken from their families, the majority of them have grown to become thriving adults.
Children languish for years in foster care
It wouldn’t have happened had they stayed in the system. Each year, more than 600,000 kids spend time in foster care. Even one day in foster care is proven to be disastrous for a kid’s longterm outcomes. But 60% of children in foster care are in the system for more than a year.
Up to 4 out of 5 foster kids have mental health issues, and 1 in 5 who age out of foster care become homeless before age 20.
I survived the foster care system. Dismantling it altogether is the only path forward.
These horrible outcomes happen despite decades of reform efforts and largescale funding. Combined federal, state and local spending for child welfare services, which is largely about foster care, soared by about 120% between the mid1990s and 2020 .
The federal government is paying for more programs on everything from mental health to substance abuse to skills training. Despite this massive investment, foster care still looks like an unsolvable problem.
But this problem is solvable. The town of Possum Trot showed how.
Strong communities hold key to solving big problems
The solution to foster care − and all of America’s biggest problems − is the power of relationships. Social scientists call it “social capital,” while others call it “strong communities." Whatever name you use, we’re talking about people helping people on an individual basis. And while that seems small, when you scale up relationships nationwide, it’s the biggest solution imaginable.
In Possum Trot, a single church changed the lives of dozens of families and children. But there are nearly 400,000 churches in America. If each one helped just one of the roughly 400,000 kids in foster care at any one time, the problem could be largely solved overnight.
And it’s not just about religious institutions. There are accessible ways for people to save kids from the lifelong struggles of foster care, all through the power of people helping people.
Americans are running away from church. But we don't have to run from each other.
I’ve seen the proof in communities across the nation.
National Angels provides local support to foster families, making them 50% more likely to avoid burnout while providing more stability for the kids. Another group, Safe Families , helps kids avoid foster care altogether, pairing trusted families with moms and dads who are struggling to provide for their kids. They take care of the kids for a few weeks or months while the parents get back on their feet.
Remarkably, most of the families are reunited, compared with less than half in foster care . In both cases, the relationships made all the difference.

Then there’s CarePortal . It connects local churches and community members with struggling families in real time, getting them the resources they need to provide for their kids. If a family can’t afford food, car seats or anything else their kids urgently need, neighbors swoop in so that child services doesn’t need to.
Surely there are many other groups I don’t know about that are making a big difference by applying the same insight.
Can something similar happen with other seemingly unsolvable problems? Absolutely. Homelessness, addiction, gang violence, poverty − they’re all made worse by the loss of community. The solution is to create community, which all of us can do. No amount of government spending or programming has done that, nor can it, for the simple reason that government action isn’t big enough. The bigger and better solution starts somewhere much smaller yet much more powerful: everyday Americans.

Mathematicians Are Edging Close to Solving One of the World's 7 Hardest Math Problems
And there’s $1 million at stake.
 In new research, mathematicians have narrowed down one of the biggest outstanding problems in math.
 Huge breakthroughs in math and science are usually the work of many people over many years.
 Seven math problems were given a $1 million bounty each in 2000, and just one has been solved so far.
The “Millennium Problems” are seven infamously intractable math problems laid out in the year 2000 by the prestigious Clay Institute, each with $1 million attached as payment for a solution. They span all areas of math , as the Clay Institute was founded in 1998 to push the entire field forward with financial support for researchers and important breakthroughs.
But the only solved Millennium Problem so far, the Poincare conjecture, illustrates one of the funny pitfalls inherent to offering a large cash prize for math. The winner, Grigori Perelman, refused the Clay prize as well as the prestigious Fields Medal. He withdrew from mathematics and public life in 2006, and even in 2010, he still insisted his contribution was the same as the mathematician whose work laid the foundation on which he built his proof, Richard Hamilton.
Math, all sciences, and arguably all human inquiries are filled with pairs or groups that circle the same finding at the same time until one officially makes the breakthrough. Think about Sir Isaac Newton and Gottfried Leibniz, whose backandforth about calculus led to the combined version of the field we still study today. Rosalind Franklin is now mentioned in the same breath as her fellow discoverers of DNA, James Watson and Francis Crick. Even the Bechdel Test for women in media is sometimes called the BechdelWallace Test, because humans are almost always in collaboration.
That’s what makes this new paper so important. Two mathematicians—Larry Guth of the Massachusetts Institute of Technology (MIT) and James Maynard of the University of Oxford—collaborated on the new finding about how certain polynomials are formed and how they reach out into the number line. Maynard is just 37, and won the Fields Medal himself in 2022. Guth, a decade older, has won a number of important prizes with a little less name recognition.
The Riemann hypothesis is not directly related to prime numbers , but it has implications that ripple through number theory in different ways (including with prime numbers). Basically, it deals with where and how the graph of a certain function of complex numbers crosses back and forth across axes. The points where the function crosses an axis is called a “zero,” and the frequency with which those zeroes appear is called the zero density.
In the far reaches of the number line, prime numbers become less and less predictable (in the proverbial sense). They are not, so far, predictable in the literal sense—a fact that is an underpinning of modern encryption , where data is protected by enormous strings of integers made by multiplying enormous prime numbers together. The idea of a periodic table of primes, of any kind of template that could help mathematicians better understand where and how large primes cluster together or not, is a holy grail.
In the new paper, Maynard and Guth focus on a new limitation of Dirichlet polynomials. These are special series of complex numbers that many believe are of the same type as the function involved in the Riemann hypothesis involves. In the paper, they claim they’ve proven that these polynomials have a certain number of large values, or solutions , within a tighter range than before.
In other words, if we knew there might be an estimated three Dirichlet values between 50 and 100 before, now we may know that range to be between 60 and 90 instead. The eye exam just switched a blurry plate for a slightly less blurry one, but we still haven’t found the perfect prescription. “If one knows some more structure about the set of large values of a Dirichlet polynomial, then one can hope to have improved bound,” Maynard and Guth conclude.
No, this is not a final proof of the Riemann hypothesis. But no one is suggesting it is. In advanced math, narrowing things down is also vital. Indeed, even finding out that a promising idea turns out to be wrong can have a lot of value—as it has a number of times in the related Twin Primes Conjecture that still eludes mathematicians.
In a collaboration that has lasted 160 years and counting, mathematicians continue to take each step together and then, hopefully, compare notes.
