[3 -8] [-2 3]
[3 -4] [0 1]

Answer 1

A-B \[=\left[\begin{matrix}6 & -1 \\ 3 & -8 \\ 3 & -4\end{matrix}\right] - \left[\begin{matrix}-4 & 2 \\ -2 & 3 \\ 0 & 1\end{matrix}\right]\]\[=\left[\begin{matrix}6-(-4) & -1-2 \\ 3-(-2) & -8-3 \\ 3-0 & -4-1\end{matrix}\right]\]\[=\left[\begin{matrix}6+4 & -1-2 \\ 3+2 & -8-3 \\ 3 & -4-1\end{matrix}\right]\]\[=...?\]
