Answer

$\left[\begin{matrix} 4& 4 &-5\\ -1& 5 &4 \end{matrix}\right]$

Work Step by Step

The given matrices are $A=\left[\begin{matrix} 0& 3 &-5\\ 1& 2 &6 \end{matrix}\right]$ $B=\left[\begin{matrix} 4& 1 &0\\ -2& 3 &-2 \end{matrix}\right]$ Add corresponding entries/elements. $\Rightarrow A+B=\left[\begin{matrix} 0+4& 3+1 &-5+0\\ 1-2& 2+3 &6-2 \end{matrix}\right]$ Simplify. $\Rightarrow A+B=\left[\begin{matrix} 4& 4 &-5\\ -1& 5 &4 \end{matrix}\right].$
