$[\begin{array}{c} - 4 n & n + m \\ - 2 n & - 4 n \end{array}] + [\begin{array}{c} 4 & - 5 \\ 3 m & 0 \end{array}]$

Step 1

Add the corresponding elements.

$[\begin{array}{c} - 4 n + 4 & n + m - 5 \\ - 2 n + 3 m & - 4 n + 0 \end{array}]$

Step 2

Add $- 4 n$ and $0$ .

$[\begin{array}{c} - 4 n + 4 & n + m - 5 \\ - 2 n + 3 m & - 4 n \end{array}]$
