Explain how to find the range

Biggest Number of Set minus Smallest Number

Because if 3-8 is 5, there is 5 numbers there, so the range is 5

Step-by-step explanation:

Put all of your numbers in order of lowest to highest and the range will be the lowest number - the highest number.

example:

43 25 67 89 22 73 45 58 32 76

Sort out into an order:

22 25 32 43 45 58 67 73 76 89

The range would be:

22-89
