#### Work Step by Step

The first pair of parenthesis contains a subtraction equation. That equation is worked first in the order of operations. The second pair of parenthesis is simply identifying a negative number so has no impact on order of operations.

=$-3-2+(-5)\longrightarrow$ solve from left to right
=$-5+(-5)\longrightarrow$
=-10
