To find the sum of two matrices, add the corresponding elements from each matrix. For the given matrices:- $ (-8) + 8 = 0 $, $ 2 + (-4) = -2 $- $ 9 + (-2) = 7 $, $ 4 + (-2) = 2 $- $ 8 + 7 = 15 $, $ -1 + 2 = 1 $Thus, the sum is $\left[ \begin{array} { r r } 0 & - 2 \ 7 & 2 \ 15 & 1 \end{array} \right]$.
