Why will the percent of change always be represented By a positive number

barxatty [35]

The percent of change will always be represented by a positive number because that change is an absolute value. Absolute values will always stay positive because the direction is ignored. It's not like a -1 or a -2, but it's a zero or a 3.
Hope this helped you out! :D
