Subtracting Integers
Subtracting integers by adding the opposite \begin{align} 5 - 9 & &&\textit{Given} \\ 5 - 9 &= 5 + {\color{red}(-9)} &&\textit{Add the opposite} \\ &= - 4 &&\textit{Solution} \\ \end{align} Guided Practice Use a number line to find each difference. Note: “Difference” is the answer to a subtraction problem. \begin{align} 4-7 &= \tag 1 \\ -6-5 &= \tag 2 \\ 2-(-4) &= \tag 3 \\ -8-(-2) &= \tag 4 \end{align}
