Samantha had to add this group of numbers (47 + 56 + 53), but she wanted to add them as quickly and as easily as possible. Here is how she decided to add the numbers:

47 + 56 + 53 = (47 + 53) + 56 = 100 + 56 = 156.

Which number property allowed her to add the numbers in this way?

the Associative Property of Addition

the Commutative Property of Addition

the Identity Property of Addition
