Chapter 1 – Calculation Basics
Using the Mouse Method (Subtraction) Figure 14 shows a subtraction story problem. In this case, you will want to set up a formula that subtracts B5 from B4. In this example, you will use the mouse for entering parts of the formula. 1. As before, you will have to type the equals sign on the keyboard to start the formula. Figure 14
Formulas start with an equals sign
2. After typing the equals sign, use the mouse to touch cell B4. Because you are in formula entry mode, the formula in cell B6 automatically types B4 for you. Figure 15

3. Now, back on the keyboard, type the minus sign. Notice that when you type the minus sign, the flashing dots around B4 become a solid blue color. Excel is waiting for you to touch another cell with the mouse. Figure 16
A solid blue box indicates that Excel is waiting for your input.
Tip: If your keyboard has a numeric keypad, the upper right keys on the keypad will let you type the common operator keys without using the Shift key.
4. With the mouse, touch the 30 in cell B5. Excel will enter B5 in the formula. Figure 17
Excel automatically enters the cell location you click on with the mouse.
