Answer

8

Work Step by Step

To add $11+(-3)$, we can take the absolute value of both numbers. $|11|=11$ $|-3|=3$ Next, we can subtract the lesser absolute value from the greater absolute value. $11-3=8$ The number with the greater absolute value is positive, so the result will be positive. Therefore, $11+(-3)=8$.
