Here are the correct matches for each equation and the property of addition it represents:
-
(14 + 6) + 8 = 14 + (6 + 8)
- Property of Addition: Associative Property
-
12 + 0 = 12
- Property of Addition: Identity Property
-
13 + 77 + 18 = 77 + 18 + 13
- Property of Addition: Commutative Property
So the matches are:
- (14 + 6) + 8 = 14 + (6 + 8) → Associative Property
- 12 + 0 = 12 → Identity Property
- 13 + 77 + 18 = 77 + 18 + 13 → Commutative Property
