use PEMDAS, multiply first, then do the absolute value,once you have one number on top, one on the bottom, divide and you will get thre3

is it -8 or just 8

those straight lines are absolute values, they mean how far the number is away from 0. They also act like parenthesis, so you do is the inside first, then you apply absolute value, which is turn it (+). 3-11=-8 I-8I=8
