Question

(11.5) - (-11.5)

Jamal says he thinks the answer is 23. His friend, Reggie, claims the
answer will be 0.
Do you agree with either of them?
explain as long as you can

Answer 1

I agree with Jamal because Reggie was doing subtract a positive by a positive but the question is a positive minus a negative, by doing absolute value you can see they both have the same value just inverse so in this case the answer would be a positive

Answer 2

Jamal is correct.

Explanation:

(11.5) − (−11.5)

=11.5 − (−11.5)

=11.5 + 11.5

=23
