Simplify the expression 4|-4|
Naddik [55]

An absolute value means something distance from 0, so |8| = 8 because the distance of 8 from 0 is 8. However the |-8| still equals 8 because the distance from -8 to 0 is 8

So with that in mind, we know that |-4| is 4 because the distance -4 is from 0 is 4

So we have 4*4 = 16
