Question
A = `[(1, 2),(3, 4)] and "B" = [(6, 1),(1, 1)], "C" = [(-2, -3),(0, 1)]` find each of the following and state if they are equal.CA + B
Solution
CA + B
CA = `[(-2, -3),(0, 1)] [(1, 2),(3, 4)]`
= `[(-2 - 9, -4 - 12),(0 + 3, 0 + 4)]`
= `[(-11, -16),(3, 4)]`
CA + B = `[(-11, -16),(3, 4)] + [(6, 1),(1, 1)]`
= `[(-11 + 6, -16 + 1),(3 + 1, 4 + 1)]`
= `[(-5, -15),(4, 5)]`.
