# How do you simplify [(3,7), (-2,1)]-[(2,5),(-3,-4)]?

The answer is $\left(\begin{matrix}1 & 2 \\ 1 & 5\end{matrix}\right)$
$\left(\begin{matrix}3 & 7 \\ - 2 & 1\end{matrix}\right) - \left(\begin{matrix}2 & 5 \\ - 3 & - 4\end{matrix}\right) = \left(\begin{matrix}3 - 2 & 7 - 5 \\ - 2 + 3 & 1 + 4\end{matrix}\right) = \left(\begin{matrix}1 & 2 \\ 1 & 5\end{matrix}\right)$
