Explicação passo-a-passo:

$a) 2 * (\left[\begin{array}{ccc}3&-1\\1&2\\0&3\end{array}\right] ) + \left[\begin{array}{ccc}5&3\\4&1\\3&0\end{array}\right] = \left[\begin{array}{ccc}11&1\\6&5\\3&6\end{array}\right]$

$b) \left[\begin{array}{ccc}5&3\\4&1\\3&0\end{array}\right] - \left[\begin{array}{ccc}3&-1\\1&2\\0&3\end{array}\right] = \left[\begin{array}{ccc}2&4\\3&-1\\3&-3\end{array}\right]$
