Question

Determine a matriz resultando de A(B+C)

Answer 1

$\left[\begin{array}{ccc}8&11\\3&6\end{array}\right] + \left[\begin{array}{ccc}2&4\\10&7\end{array}\right] = \left[\begin{array}{ccc}10&15\\13&13\end{array}\right]$

     B                   C                (B+C)

$\left[\begin{array}{ccc}12&1\\9&5\end{array}\right] - \left[\begin{array}{ccc}10&15\\13&13\end{array}\right] = \left[\begin{array}{ccc}2&-14\\-4&-8\end{array}\right]$

    A                 (B+C)              A-(B+C)
