To calculate the average (also known as the mean) of a set of numbers, you follow these steps:

1. Add up all the numbers in the set.
2. Divide the sum by the total number of values in the set.

The formula for the average is:

$\text{Average} = \frac{\text{Sum of all numbers}}{\text{Number of values}}$
