Question

Evaluate the expression −11−(−7−9) by rewriting the subtraction as addition

Answer 1

Answer:

5

Step-by-step explanation:

Let's rewrite this a bit.

$-11-(-7-9)=-11+7+9$

This is because there is a -1 before the expression inside the parentheses, so every sign is reversed.

Now we can add.

$-11+7+9=5$
