Answer
$\left[\begin{array}{rr}
-2 & -3
\\
3 & -1
\\
3 & -4
\end{array}\right]
$
Work Step by Step
Subtracting each corresponding element, then the given matrix expression simplifies to
$$\begin{aligned}
&
\left[\begin{array}{rr}
0-2 & -3-0
\\
2-(-1) & 0-1
\\
1-(-2) & -1-3
\end{array}\right]
\\&=
\left[\begin{array}{rr}
-2 & -3
\\
3 & -1
\\
3 & -4
\end{array}\right]
.\end{aligned}
$$
