Answer
$\begin{bmatrix}
-4 & 2 & -5\\
3 & -1 & 8
\end{bmatrix}$
Work Step by Step
Since, matrices $A$ 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:
$A-B=\begin{bmatrix}
0-4 & 3-1 & -5-0\\
1-(-2) & 2-3 & 6-(-2)
\end{bmatrix} \\ =\begin{bmatrix}
-4 & 2 & -5\\
3 & -1 & 8
\end{bmatrix}$
