Answer
$\left[\begin{array}{rrr}
-4 & 2 & -5\\
3 & -1 & 8
\end{array}\right]$
Work Step by Step
$A=\left[\begin{array}{lll}
0 & 3 & -5\\
1 & 2 & 6
\end{array}\right],\quad B=\left[\begin{array}{lll}
4 & 1 & 0\\
-2 & 3 & -2
\end{array}\right],\quad C=\left[\begin{array}{ll}
4 & 1\\
6 & 2\\
-2 & 3
\end{array}\right]$

A and B are both 2 by 3 matrices, so $A-B$ is defined.
If C=A-B, $\quad c_{ij}=a_{ij}-b_{ij}$
$A-B=\left[\begin{array}{lll}
0-4 & 3-1 & -5-0\\
1-(-2) & 2-3 & 6-(-2)
\end{array}\right]$
$=\left[\begin{array}{rrr}
-4 & 2 & -5\\
3 & -1 & 8
\end{array}\right]$
