To simplify the expression \( 13 - 2(1 - 15)/4 \), the first step is to simplify the expression inside the parentheses.
- Calculate \( 1 - 15 \): \[ 1 - 15 = -14 \]
Now, we can rewrite the expression: \[ 13 - 2(-14)/4 \]
At this point, you can proceed by multiplying \( -2 \) with \( -14 \) next or continue simplifying, but the very first step was simplifying the parentheses.
