Question 8972
Is this absolute value?  If so, and for future reference, there is a vertical line on the keyboard above the backslash.


Anyway, I think what you mean is this:
 -|-11 + 6 |


Do the -11 + 6 inside the vertical bars first.
-|-5|


The absolute value of -5 is 5, so this leaves:
-|-5| = -5
