Simplify the Matrix A=[[1,1],[2,6]]B=[[-1,9],[6,-2]]

$A = [\begin{array}{c} 1 & 1 \\ 2 & 6 \end{array}] B = [\begin{array}{c} - 1 & 9 \\ 6 & - 2 \end{array}]$

Add the corresponding elements.

$[\begin{array}{c} 1 - 1 & 1 + 9 \\ 2 + 6 & 6 - 2 \end{array}] + A = =$

Simplify each element of the matrix $[\begin{array}{c} 1 - 1 & 1 + 9 \\ 2 + 6 & 6 - 2 \end{array}]$ .
