Answer 1

$\left[\begin{array}{ccc}9&10&0\\8&1&8\\7&5&0\end{array}\right] + \left[\begin{array}{ccc}-3&-8&-3\\-5&-10&-2\\-7&-5&-1\end{array}\right] = \left[\begin{array}{ccc}6&2&-3\\3&-9&6\\0&0&-1\end{array}\right]$

Answer 2

$\left[\begin{array}{ccc}9&10&0\\8&1&8\\7&5&0\end{array}\right] + \left[\begin{array}{ccc}-3&-8&-3\\-5&-10&-2\\-7&-5&-1\end{array}\right] = \left[\begin{array}{ccc}9-3&10-8&0-3\\8-5&1-10&8-2\\7-7&5-5&0-1\end{array}\right]$
$A+B = \left[\begin{array}{ccc}6&2&-3\\3&-9&6\\0&0&-1\end{array}\right]$
