Acá te dejo las respuestas:

a) $\left[\begin{array}{ccc}1&3\\-1&2\end{array}\right]+\left[\begin{array}{ccc}1&3\\2&-3\end{array}\right]=\left[\begin{array}{ccc}1+1&3+3\\(-1)+2&2+(-3)\end{array}\right]=\left[\begin{array}{ccc}2&6\\1&-1\end{array}\right]$

b) $\left[\begin{array}{ccc}1&3\\-1&2\end{array}\right]-\left[\begin{array}{ccc}1&3\\2&-3\end{array}\right]=\left[\begin{array}{ccc}1-1&3-3\\(-1)-2&2-(-3)\end{array}\right]=\left[\begin{array}{ccc}0&0\\-3&5\end{array}\right]$

c) $\left[\begin{array}{ccc}1&3\\-1&2\end{array}\right]*\left[\begin{array}{ccc}1&3&2\\2&-3&-1\end{array}\right]=\left[\begin{array}{ccc}(1*1)+(3*2)&(1*3)+(3*(-3))&(1*2)+(3*(-1))\\(-1*1)+(2*2)&(-1*3)+(2*(-3))&(-1*2)+(2*-1)\end{array}\right]$

$=\left[\begin{array}{ccc}7&-6&-1\\-3&-9&-4\end{array}\right]$

d) $\left[\begin{array}{ccc}1&2\\-1&0\end{array}\right]+\left[\begin{array}{ccc}-2&9\\3&5\end{array}\right]=\left[\begin{array}{ccc}1+(-2)&2+9\\-1+3&0+5\end{array}\right]=\left[\begin{array}{ccc}-1&11\\2&5\end{array}\right]$
