Question

Calcule a soma e a subtração das matrizes A e B:

Answer 1

Resposta:

0 + 1 = 1       1 + 4 = 5

2 - 6 = -4     3 + 9 = 12

0 - 1 = -1       1 -= 4 = -3

2-(-6) = 8     3 - 9 = -6

$A+B=\left(\begin{array}{ccc}1~~~~~~ 5\\-4~~~~12\end{array}\right)\\\\A-B=\left(\begin{array}{ccc}-1~~~-3\\8~~~~~-6\end{array}\right)$
