How to find the range of the numbers 88,86,88,89,86,90,90,92,90,90

Okay, so to find the range, you must subtract the biggest number minus the smallest number, which will be 92 - 86, which is 6, so your range = 6.
Easy and simple like that. :-)
I hope I helped! =D

The range is the difference between the numbers. To find this you do the biggest number minus the smallest number. You are left with the difference between them. The biggest number is 92 and the smallest number is 86 so you do 92-86 which equals 6.

The answer is “faster”.
