Answer 3

Since the | | is between X, that means it is asking for the absolute value. The end result for All numbers and signs in the absolute value sign will be positive. This means that |2-100| is equal to positive 98, since 2-100=-98, and the absolute value of 98 would be positive 98. The same thing goes for |-2| and |2|, they both have the same answer.
