Answer
$\begin{bmatrix}
4 & 4 & -5\\
-1 & 5 & 4
\end{bmatrix}$
Work Step by Step
Since, matrix $A$ and $B$ are both $ 2 \times 3$ matrices and have the same dimensions, we know that their addition, $A+B$, is defined.
Thus, we have:
$A+B=\begin{bmatrix}
0+4 & 3+1 & -5+0\\
1+(-2) & 2+3 & 6+(-2)
\end{bmatrix} \\ =\begin{bmatrix}
4 & 4 & -5\\
-1 & 5 & 4
\end{bmatrix}$
