Question

Which equations illustrate the associative property of addition? Choose exactly two answers that are correct.

Answer 1

Solutions 

Associative Property is a rule that refers to grouping. The rule is "a + (b + c) = (a + b) + c". 

The correct answers are (A) and (D) 

(A) =  (11 + 2.2) + (–5) = 11 + [2.2 + (–5)] 

(D) = –7 + [4 + (–2.1 • 6)] = (–7 + 4) + (–2.1 • 6)
