Answer 1

$a) \left[\begin{array}{ccc}1&3\\4&-6\end{array}\right] + \left[\begin{array}{ccc}7&8\\-5&1\end{array}\right] = \left[\begin{array}{ccc}8&5\\-1&-5\end{array}\right]$

$\left[\begin{array}{ccc}1&3\\4&-6\end{array}\right] - \left[\begin{array}{ccc}7&8\\-5&1\end{array}\right] = \left[\begin{array}{ccc}-6&-5\\9&-7\end{array}\right]$

$b) \left[\begin{array}{ccc}1&-3\\-4&6\end{array}\right] + \left[\begin{array}{ccc}-7&8\\5&-1\end{array}\right] = \left[\begin{array}{ccc}-6&5\\1&5\end{array}\right]$

$\left[\begin{array}{ccc}1&-3\\-4&6\end{array}\right] - \left[\begin{array}{ccc}-7&8\\5&-1\end{array}\right] = \left[\begin{array}{ccc}8&-11\\-9&7\end{array}\right]$
