 Question 1: Which of the following is an example of Commutative Property of addition? 2 + 7 = 9 − 2 2 + 7 = 7 + 2 7 × 1 = 7 ( 2 + 7 ) + 3 = 7 + ( 3 + 2)
 Question 2: Which is an example of Identity Property of addition? 2 + 3 = 3 + 2 1 × 6 = 6 (1 + 2) + 3 = (2 + 3) + 1 6 + 0 = 6
 Question 3: Which is an example of Associative Property of addition? 3 + ( 4 + 5) = (3 + 4) + 5 5 + 3 = 3 + 5 3 + 0 = 3 3 + (−3) = 0
 Question 4: Which statement is NOT correct? Changing the groupings of the addends will not affect the sum. Changing the order of the addends will not affect the sum. Changing the groupings of the addends will affect the sum. When you add 0 to any real number, the sum is the number itself.
