Chapter 3: Perform calculations on data
You can perform mathematical operations on numbers by using the mathematical
operators for addition (+), subtraction (–), multiplication (*), division (/), negation (-),
and exponentiation (^). You can perform other operations on a range of numbers by
using the following Excel functions:
■ SUM Returns the sum of the numbers.
■ AVERAGE Returns the average of the numbers.
■ COUNT Returns the number of entries in the cell range.
■ MAX Returns the largest number.
■ MIN Returns the smallest number.
These functions are available from the AutoSum list, which is in the Editing group on
the Home tab of the ribbon and in the Function Library group on the Formulas tab.
The Function Library is also where you’ll find the rest of the Excel functions, organized
into categories.
Excel includes a wide variety of functions
The Formula AutoComplete feature simplifies the process of referencing functions,
named ranges, and tables in formulas. It provides a template for you to follow and
suggests entries for each function argument. Here’s how it works:
1. As you begin to enter a function name after the equal sign, Excel displays a list
of functions matching the characters you’ve entered. You can select a function
from the list and then press Tab to enter the function name and the opening
parenthesis in the cell or formula bar.
