(There are brackets around the the numbers below for each matrix)

a)

$$\left[ \begin{matrix} 3 & -1 & 5 \\ -2 & 4 & 6 \\ \end{matrix} \right]-\left[ \begin{matrix} 1 & -2 & 2 \\ -2 & 3 & 4 \\ \end{matrix} \right]$$

b)

$$\left[ \begin{matrix} 6 & 4 \\ 2 & 5 \\ -1 & 3 \\ \end{matrix} \right]+\left[ \begin{matrix} 2 & 3 \\ 2 & -2 \\ \end{matrix} \right]$$

c)
$$\left[ \begin{matrix} 2 & -3 & 4 \\ -2 & 3 & 4 \\ \end{matrix} \right]\times \left[ \begin{matrix} -3 & 2 \\ 4 & 1 \\ \end{matrix} \right]$$

d)

$\left[ \begin{matrix} 3 & -2 & 2 \\ 4 & -3 & 3 \\ \end{matrix} \right]\times \left[ \begin{matrix} 3 & -2 \\ 1 & -2 \\ 0 & 4 \\ \end{matrix} \right]$
