1998 CEMC Gauss (Grade 7) Problems/Problem 9

Problem

Two numbers have a sum of 32. If one of the numbers is – 36, what is the other number?

$\text{(A)}\ 68 \qquad \text{(B)}\ -4 \qquad \text{(C)}\ 4 \qquad \text{(D)}\ 72 \qquad \text{(E)}\ -68$

Solution

The other number is $32 - (-36) = \boxed{68},$ so the answer is $\text{(A)}.$
