# If A = (1, 2),(3, 4), B = (6, 1), (1, 1) and C= (-2, -3),(0, 1) Find the Following and State of They Are Equal Ca + B - Mathematics

Sum

If A = [(1, 2),(3, 4)], B = [(6, 1), (1, 1)] and C= [(-2, -3),(0, 1)] Find the following and state of they are equal CA + B

#### Solution

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)] = [(-5, -15),(4, 5)]
