$tt A=left[begin{array}{ccc}2&3\4&3\end{array}right]\\\B=left[begin{array}{ccc}7&8\4&3\end{array}right]$

A + B :

$tt left[begin{array}{ccc}2&3\4&3\end{array}right]+left[begin{array}{ccc}7&8\4&3\end{array}right]\\\\=left[begin{array}{ccc}2+7&3+8\4+4&3+3\end{array}right] \\\= left[begin{array}{ccc}9&11\8&6\end{array}right]$

Jadi, hasil A + B adalah $tt left[begin{array}{ccc}9&11\8&6\end{array}right]$
