Answer 2

Subtração entre matrizes:

Sejam as matrizes A e B:

        $A = \left[\begin{array}{cc}-5&8\\76&3\end{array}\right]$

        $B = \left[\begin{array}{cc}0&2\\-86&54\end{array}\right]$

Calculando a diferença entre A e B temos:

 $A - B = \left[\begin{array}{cc}-5-0&8-2\\76-(-86)&3-54\end{array}\right]$

            $= \left[\begin{array}{cc}-5&6\\162&-51\end{array}\right]$
