To add two matrices, add their corresponding elements. For the given matrices, the sum is calculated as follows:$$\left[ \begin{array} { r r } - 1 & - 7 \3 & 5 \- 2 & 7\end{array} \right] + \left[ \begin{array} { r r } - 4 & 1 \5 & 3 \- 1 & - 7\end{array} \right] = \left[ \begin{array} { r r } - 1 - 4 & - 7 + 1 \3 + 5 & 5 + 3 \- 2 - 1 & 7 - 7\end{array} \right] = \left[ \begin{array} { r r } - 5 & - 6 \8 & 8 \- 3 & 0\end{array} \right]$$
