Question

Dadas as matrizes
A= 0 3 B= -2 4 e C= 4 2
2 -5 0 -1 -6 0

Calcule
A + B

Answer 1

$A+B=\left[\begin{array}{ccc}0&3\\2&-5\end{array}\right] +\left[\begin{array}{ccc}-2&4\\0&-1\end{array}\right]$
Na soma de matriz, é só somar o termo correspondente a cada posição:
$A+B= \left[\begin{array}{ccc}0-2&3+4\\2+0&-5-1\\\end{array}\right] \\ A+B= \left[\begin{array}{ccc}-2&7\\2&-6\\\end{array}\right]$
