Answer

$-3$

Work Step by Step

The numbers being added have different signs. To add these numbers, perform the following steps: (1) Subtract the smaller absolute value to the bigger absolute value to obtain: $|-11| - |8| = 11-8 = 3$ (2) The sum will have the same sign as the number with the bigger absolute value. Since $|-11| \gt |8|$, then the sum will be negative. Thus, 8+(-11) = -3\$
