Properties of Addition
Commutative property: When two numbers are added together, the order of addends does not affect the sum or result. For example, 8 + 4 = 4 + 8.
Associative Property: When three or more numbers are added, the grouping of addends does not affect the sum or result. For example, 4 + (3 + 7) = (4 + 3) + 7.
Identity Property: The sum of zero and any other number is the number itself. For example, 5 + 0 = 5.
