Question

Write and expression using absolute value to represent finding the distance between -3 and -7

Answer 1

|-3--7| = |-3+7| = |4| = |-7--3| = |-7+3|= |-4| = 4

absolute value is always positive

absolute value = +sqr(x^2)

or a more usual definition of absolute value is

|x| = x if x>0

|x| =-x if x<0

if x=0 |x|=0
