If A= [(2, 3) (5, -4) (-6, 1)], B = [(-1, 2) (2, 2) (0, 3)] and C = [(4, 3) (-1, 4) (-2, 1)] show that A+B=B+A

Question

If A =\(\begin{vmatrix}2&-3\\5&-4\\-6&1\end{vmatrix}, B = \begin{vmatrix}-1&2\\2&2\\0&3\end{vmatrix} and\, C= \begin{vmatrix}4&3\\-1&4\\-2&1\end{vmatrix}\)

show that A+B=B+A

A= [(2, 3) (5, -4) (-6, 1)], B = [(-1, 2) (2, 2) (0, 3)] and C = [(4, 3) (-1, 4) (-2, 1)]

Answer 1

From (i) and (ii), we get A + B = B + A
