Chapter 4 – Formula

Anatomy of a formula:A basic formula consists of a combination of cell references, constants and operators. Every formula begins with an equal (=) symbol. Formula can be divided into two types: (1) built-in functions or (2) Tailor-made

Built-in Functions

You can simply to click the icon next to the formula box to bring out the formula dialog box. In the formulas dialog box, you can choose a function by clicking an icon.

Step 1: Select the cell E2. Step 2: Click the button next to the formula box. Step 3: Choose the “SUM” in the function dialog box. Step 4: Select the cells to be summed up, e.g. (B2:D2), and then press the enter.

Built-in Function – Sum

Step 4

Step 1: Select the cell F2. Step 2: Click the button next to the formula box. Step 3: Choose the “AVERAGE” in the function dialog box. Step 4: Select the cells to be summed up, e.g. (B2:D2), and then press the enter.
