Let's break it down step by step! First, evaluate the expressions inside the parentheses: 1. For \( -(4-5) \): - Calculate \( 4 - 5 = -1 \) - Thus, \( -(-1) = 1 \) 2. Now for \( -(7-8) \): - Calculate \( 7 - 8 = -1 \) - Thus, \( -(-1) = 1 \) Now combine the results: \[ 1 + 1 = 2 \] So the simplified expression is \( 2 \).
