Answer 2

A = $\left[\begin{array}{ccc}-2&0\\3&1\end{array}\right]$
B = $\left[\begin{array}{ccc}1&10\\2&6\end{array}\right]$

a) A + B = $\left[\begin{array}{ccc}-2&0\\3&1\end{array}\right]+ \left[\begin{array}{ccc}1&10\\2&6\end{array}\right] = \left[\begin{array}{ccc}-1&10\\5&7\end{array}\right]$

b) 2A = $2 \ \left[\begin{array}{ccc}-2&0\\3&1\end{array}\right] = \left[\begin{array}{ccc}-4&0\\6&2\end{array}\right]$
