-7

Explanation:

In regard to the order of operations, absolute value bars (#||#) take the same precedence as parentheses. That means we take the absolute value of #-7# first, which means to find the distance from that number to 0 (basically, this converts any number into a positive number), leaving us with:

Explanation:

You would first do the absolute value of #-7# and then multiply the absolute value of #-7# by #-1#.

#-|-7|#

#-(7)#

#-7#

  1. Find the absolute value of #-7#, which is #7#.
  2. Multiply the absolute value of #-7# by #-1#. Since the absolute value of #-7# is #7# and #7*-1# is #-7#, the answer is #-7#.
