Are you sure?

OpenStudy (rhr12):

Because its a absolute value term

jimthompson5910 (jim_thompson5910):

Find the distance between x and y step 1) subtract x and y step 2) apply absolute value to ensure the result is never negative (negative distance makes no sense)

OpenStudy (rhr12):

yes, pretty much.

jimthompson5910 (jim_thompson5910):

example: find the distance between 2 and 9 step 1) 2 - 9 = -7 step 2) |-7| = 7 is the distance between the two values on the number line
