Question

If A= (3 6 4 -4 5 0 ) and B = (2 3 4 -5 6 2) the determine A+B and A-B​

Answer 1

the orders of both matrix is same...

so, additional and substraction is possible

A + B = (3 6 4 -4 5 0) + (2 3 4 -5 6 2)

= (5 9 16 -9 11 2)

A - B = (3 6 4 -4 5 0) - (2 3 4 -5 6 2)

= (1 3 0 -(-1) -1 -2)
