Question

If A = `[(1, 9),(3, 4),(8, -3)]`, B = `[(5, 7),(3, 3),(1, 0)]` then verify that A + B = B + A

Answer 1

A + B = `[(1, 9),(3, 4),(8, -3)] + [(5, 7),(3, 3),(1, 0)]`

= `[(6, 16),(6, 7),(9, -3)]`  ...(1)

B + A = `[(5, 7),(3, 3),(1, 0)] + [(1, 9),(3, 4),(8, 3)]`

= `[(6, 16),(9, 7),(9, -3)]`  ....(2)

From (1) and (2) we get A + B = B + A
