Answer 1

Respuesta:

sumas:

$\left[\begin{array}{ccc}1&8&4\\4&2&6\\7&9&7\end{array}\right] + \left[\begin{array}{ccc}7&8&1\\2&5&6\\11&6&0\end{array}\right] =\left[\begin{array}{ccc}8&16&5\\6&7&12\\18&15&7\end{array}\right]$

$\left[\begin{array}{ccc}3&8&5\\6&5&2\\10&7&4\end{array}\right] + \left[\begin{array}{ccc}7&9&5\\0&13&11\\2&8&1\end{array}\right] = \left[\begin{array}{ccc}10&17&10\\6&18&13\\12&15&5\end{array}\right]$

$\left[\begin{array}{ccc}6&4&0\\1&3&2\\5&6&9\end{array}\right] + \left[\begin{array}{ccc}6&8&1}\\8&4&0\\1&10&6\end{array}\right] = \left[\begin{array}{ccc}12&12&1\\9&7&2\\6&16&15\end{array}\right]$

restas:

$\left[\begin{array}{ccc}10&9&11\\16&4&1\\6&2&5\end{array}\right] - \left[\begin{array}{ccc}5&2&3\\9&3&1\\0&2&4\end{array}\right] = \left[\begin{array}{ccc}5&7&8\\7&1&0\\6&0&1\end{array}\right]$

$\left[\begin{array}{ccc}13&20&9\\9&23&18\\4&6&7\end{array}\right] - \left[\begin{array}{ccc}7&12&4\\1&11&14\\2&3&6\end{array}\right] = \left[\begin{array}{ccc}6&8&5\\8&12&4\\2&3&1\end{array}\right]$

$\left[\begin{array}{ccc}30&14&6\\13&20&21\\4&7&11\end{array}\right] - \left[\begin{array}{ccc}13&6&5\\5&17&14\\2&3&4\end{array}\right] =\left[\begin{array}{ccc}17&8&1\\8&3&7\\2&4&7\end{array}\right]$

multiplicación:

$\left[\begin{array}{cc}2&3\\5&6\end{array}\right] x \left[\begin{array}{cc}1&2\\9&1\end{array}\right] = \left[\begin{array}{cc}2+27&4+3\\5+54&10+5\end{array}\right] = \left[\begin{array}{cc}29&7\\59&15\end{array}\right]$
