3 Easy Ways to Insert Equation in Excel

Here, we will learn 3 easy ways to for entering equations in Excel. To describe the methods, we have used some excellent examples with screenshots and explanations. So, without further delay, let’s get started.

1. Use Equation Editor to Assign Equation in Excel

In this method, we shall learn how to use the Equation Editor for inserting equations effectively in Excel. We can use the Equation Editor both for predefined equations and also for creating a new equation as per our wish.

• For using the Equation Editor, first, go to the Insert tab.
• After that, click on Symbols.

1.1 Insert Predefined Equation

If we want to assign a predefined equation then we need to follow the steps below.

Steps:

• Firstly, Insert tab > Symbols group.
• From the Symbols group, click on the Equation dropdown.

• For this reason, a list of equations will appear.
• Now, click on the equation that you need.
• For example, we selected the equation of the Fourier Series.

• Hence, the equation will be inserted into the worksheet.

1.2 Create a New Equation

We can also create a new equation by using the Excel Equation Editor. Here, we will make the Volume formula. The formula is like the picture below.

Steps:

• First of all, select Insert tab > Symbols group.
• Accordingly, click on the Equation command.

• In turn, the Equation Editor appears.

• When the Equation Editor is selected, two contextual tabs appear in the tab list. They are Shape Format and Equation.
• However, the Equation Editor is a shape.
• So, you can format the shape using the Shape Format tab.
• The other tab is the Equation contextual tab. It will help you to insert an equation into the Equation Editor.

• To write an equation in the Equation Editor, first, go to the Equation tab.
• Consequently, you can see the Symbols and Structures group.
• You can use these Symbols and Structures in the equation.
• To see more symbols click on the More button which is located in the bottom right corner of the Symbols window.

• Click on the More button and then the window will be expanded.
• In the window, there is a drop down in the top right corner.
• Right now ‘Basic Math’ symbols are showing in the window.
• Therefore, click on the drop down to see the other symbol options.

• Except for Basic Math, you can also work with these symbol categories:

• Basic Math
• Greek Letters
• Letter-Like Symbols
• Operators
• Arrows
• Negated Relations
• Scripts
• Geometry

• If you select Greek Letters, you will get two types of Greek Letters: Lowercase Greek Letters and Uppercase Greek Letters.

• In this method, we will use the symbols of Geometry.
• After selecting Geometry from the dropdown, we can see the symbols like the screenshot below.

• There are some Structures on the right side of the Symbols group of commands which are Script type structure, then Radical, Integral, Large Operator, Bracket, Function, Accent, Limit and Log, Operator and finally the Matrix structure.

• Now, type Volume in the Equation Editor.
• Subsequently, type equal sign (=).
• You can see from the volume equation that it has a fraction.
• Forthwith, click on the Fraction dropdown from the Structures group of commands and select the Stacked Fraction.

• Thereupon, the Equation Editor will look like the image below.

• In the top blank box, type 1 and in the bottom blank box type 3.
• Later, press the right-arrow on the keyboard.
• In the Symbols drop down, select Basic Math and then the Multiplication Sign from the window.

• Moreover, there is a Pi sign in the equation.
• For inserting it, go to Symbols > Greek Letters > Lowercase > Pi symbol.
• Again, select Basic Math > Multiplication Sign.

• In the equation now is: ‘diameter divided by 2’ whole square.
• To assign it, select the Superscript structure.

• At this moment, select the first blank box in the superscript.

• Insert Parentheses with a single value from the Bracket structure.

• Eventually, the Equation Editor will look like the screenshot below.

• Select the box within parentheses.

• Click on the Stacked fraction structure again.

• At the upper box, type Diameter.
• Type just 2 at the bottom.
• Lastly, type 2 as the superscript.

• Once again, press the right-arrow on the keyboard.
• The rest is simple, a cross sign and type Height.
• Ultimately, our equation is complete.

• In the end, format the shape of the Equation Editor as you wish.

2. Using Insert Function Button

Suppose, we have a dataset (B4:E8) that contains the Names and the Marks of Test-1 & Test-2 of some students. Here, we will use the Insert Function button in Excel to calculate the Average Marks of each student. Here, we will insert an equation manually in Excel. For this, follow the steps below.

Steps:

• First of all, select cell E5.
• Then, click on the Insert Function button.

• Consequently, the Insert Function dialog box will pop up.
• Now, select AVERAGE from the Select a function.
• Click OK.

• In turn, a dialog box named Function Arguments will open.
• In this case, go to the Number1 box and select cell C5.
• After that, keep the cursor in the Number2 box and select the D5 cell.
• We can already see the result in the Formula result portion.
• Finally, click the OK button.

• In this way, we can calculate the Average Marks (E5) of the first student.

• However, double-click on the fill handle option for copying the function into the rest of the cells (E6:E8).

• Lastly, see the final output in the screenshot below.

3. Insert Equation Manually in Excel

We can also enter equations manually in a cell. Let’s say, we have a dataset (B4:E6) containing the Names and Marks of Test-1 & Test-2 of some students. Here, we need to find the Total Marks of them. The steps are below.

Steps:

• First, select cell E5.
• Secondly, to calculate Total Marks, type the following formula in this cell:

• Finally, to get the result, press the Enter key.

• There is another method to insert formulas manually.
• To apply this method, firstly, select cell E6.
• Therefore, to find the Total Marks, type equal sign (=) in the cell.
• Next type sum and so you will find the SUM function below the cell (E6).

• Thereupon, double-click on the SUM function.

• Consequently, select the range C6:D6.

• Eventually, press Enter to find the result.
• In this way, we can insert the SUM function.

How to Plot Equation in Excel Graph

Assuming, we have a dataset (B4:C8) where we can see the values of a. Here, we need to assign a formula for calculating the values of b and then plot the equation in the Excel graph. See the steps below.

Steps:

• First, select cell C5.
• Then, to calculate the value of b, type the following formula in the cell:

• After that, use the fill handle to copy the formula up to cell C8.
• Next, select the range B5:C8.
• Now, go to the Insert tab.

• Therefore, go to the Charts group.
• Click on the dropdown shown in the screenshot below.

• In turn, select any chart option as you wish.
• For example, we selected the Scatter with Smooth Lines and Markers option.

• Thus, we will get our desired graph where we have inserted an equation.

How to Edit Equation in Excel

Editing equations is a very easy task. Follow the below steps:

• Firstly, select the cell (E5) where you want to edit the equation.

• Now, put the cursor in the Formula Bar.
• After that, you can edit the equation easily.

Operator Precedence of Equation in Excel

In Excel, the operator precedence of a formula is set by default. Excel always goes through the following order for doing calculations:

• The portion of the formula that is enclosed in parentheses will be calculated first.
• Then, the calculations for division or multiplication are made.
• After that, Excel will add and subtract the remaining components of the equation.

• For our example, the formula in cell C7 is:

• In the beginning, Excel will first add C4 and C5 as it is in parentheses.
• Thereupon, it will perform the task of multiplication.
