Given 2 matrix A and B, A+B means the sum of the matrices. The sum of two matrices can be done by summing each element of the first matrix to the corresponding element of the secont matrix. So:


\begin{bmatrix}{-4} & {-5} & {-2} \\ {5} & {-3} & {4} \\ {-5} & {4} & {2}\end{bmatrix}+\begin{bmatrix}{3} & {3} & {-1} \\ {-4} & {1} & {3} \\ {5} & {4} & {2}\end{bmatrix}=\begin{bmatrix}{-4+3} & {-5+3} & {-2-1} \\ {5-4} & {-3+1} & {4+3} \\ {-5+5} & {4+4} & {2+2}\end{bmatrix}=\begin{bmatrix}{-1} & {-2} & {-3} \\ {1} & {-2} & {7} \\ {0} & {8} & {4}\end{bmatrix}
