Answer

$-8$

Work Step by Step

The addends (numbers being added have) different signs. To add two numbers with different signs, perform the following steps: (1) Subtract the smaller absolute from the bigger absolute value. $|-11|-|3|=11-3=8$ (2) Use the sign of the number with the bigger absolute value. $3+(-11)=-8$ Thus, the sum is $-8$.
