Question

11) Which is an example of Associative Property of Addition ?

A. 2 + 0 = 2
B. 8 + 3 = 3 + 8
C. 6 + (-6) = 0
D. (3 + 4) + 9 = 3 + (4 +9)

Answer 1

D. (3 + 4) + 9 = 3 + (4 +9) represents the Associative Property of Addition.

Explanation:

Associative Property of Addition states that for any groups of numbers, the order of addition does not matter.

or, for any numbers A, B and C

A + ( B +C) = (A +B) + C

Here, D. (3 + 4) + 9 = 3 + (4 +9) represents the Associative Property of Addition.
