Question 9 Consider the two expressions: a) 73 – 14 + 1, b) 73 – 14 – 1. For each of these expressions, identify the expressions from the following collection that are equal to it. (a) 73 – (14 + 1) (b) 73 – (14 – 1) (c) 73 + (– 14 + 1) (d) 73 + (– 14 – 1) Solving each expression (a) 73 – (14 + 1) = 73 – 14 – 1 (b) 73 – (14 – 1) = 73 – 14 + 1 (c) 73 + (– 14 + 1) = 73 – 14 + 1 (d) 73 + (– 14 – 1) = 73 – 14 – 1 Thus, Expression A matches with (b) and (c) Expression B matches with (a) and (d)
