The difference between two values is known as subtraction. Being able to find the difference in values is a useful calculation when comparing results from two different periods. You can also use it as the beginning of a percent-change formula. Once you have your two values, it is a matter of simple subtraction to find the difference between the values. It is useful to use a calculator to find the difference so you do not make any mistakes.
