Chapter 13. Working with Cell Formulas and Functions
Formulas in an Excel worksheet perform calculations, such as adding, subtracting, aver-
aging, or multiplying numbers. They’re also dynamic—for example, if you reference a cell
address in a formula, the formula changes if the data in the cell changes.
At times, formulas can be complex and time-consuming to build. To simplify creating for-
mulas, Excel also has a solid collection of different functions to assist you with your cal-
culations. For example, you could use the AVERAGE function to average a series of num-
bers.
