Help matrices.......?

Question

A=[6 -3] B=[5 6] C=[0 5]

{2 1} {2 -1}

determine

1) A + B

2) A – B

3) -2C

Answer 1

Greetings,

[6 -3] = A

[2 1]

[5 6] = B

[2 -1]

C = [0 5]

[11 3] = A + B, add corresponding values in each matrix

[4 0]

[1 -9] = A - B, subtract corresponding values in each matrix

[0 2]

[0 -10] = -2C, multiply each element by -2

Regards
