What is |7-3| - |3-7| =?
Im studying for an ACT and i forgot how to figure this out
|4| - |-4| =?
Because you are dealing with absolute values, both terms
must be considered to be positive. You are subtracting the
absolute value of -4, which is 4, from the absolute value of
+4, which is 4.
4 - 4 = 0
