Excel is primarily used for its spreadsheet functions but it also supports several textual functions. When evaluating an equation, for example, the area of a circle, you can do so by typing the formula in the cell using the equal sign (=). The problem arises when you want to include the equation itself. It becomes a complex process to include the Pi character or numerators and denominators within the cell. To solve this problem, Excel has some preset equations that can be used or you can write your own equation.

## Option 1 – Use a preset equation

### Step 1 – Find the equation

- Go to
**Insert > Symbols > Equation** - Select
**Binomial Theorem**

### Step 2 – Move the equation to an appropriate location

- The equation will be inserted into the file as an image
- Move the equation image to the desired location

## Option 2 – Write the equation

### Step 1 – Open the **Math Input Control **box

- Go to
**Insert > Symbols > Equation** - Select
**Ink Equation**

### Step 2 – Write the equation

- Write the equation using the mouse
- Check the preview to see if the characters are displayed correctly
- Click
**Insert**

### Step 3 – Check the result

- The equation is inserted as an image
