Chapter 2 Getting Started with Numbers 81

Adding a Quick Formula

To perform a simple calculation using values in adjacent cells, the easiest approach is

to use a quick formula. Here you’ll use a quick formula to add the values in column B of

your table and display the result in the column’s footer cell.

To add a quick formula:

1 Click cell B7, the footer cell for column B.

2 Click Function in the toolbar and choose Sum.

The value $4,000, the sum of the two numbers in column B, appears in the column’s

footer cell.

The sum changes whenever the values in column B change.

This value is calculated automatically

using a quick formula.
