-|-8|

Always work from the inside out"

1. First we look at    -8

2. Second we look at  |-8|

3. Third we look at  -|-8|

---------------------------------

1. When we look at     -8 we observe that it is a negative number.

2. When we look at    |-8| the absolute value bars make that
   -8 between the absolute value bars become 8 (positive eight)

3. When we look at   -|-8| the negative sign in front makes that 
   positive 8 from step 2 become -8 (again).

So the answer is -8.
