उत्तर

`[(2, 1),(3, 2),(-1, 1)][(1, 0, 1),(-1, 2, 1)]`

= `[(2(1) + 1(-1), 2(0) + 1(2), 2(1) + 1(1)), (3(1) + 2(-1), 3(0) + 2(2), 3(1) + 2(1)), (-1(1) + 1(-1), -1(0) + 1(2), -1(1) + 1(1))]`

= `[(2 - 1, 0 + 2, 2 + 1), (3 - 2, 0 + 4, 3 + 2),(-1 - 1, 0 + 2, -1 + 1)]`

= `[(1, 2, 3),(1, 4, 5),(-2, 2, 0)]`
