The commutative property of addition states that a + b = b + a, in other words, the numbers in an addition problem can be flipped, but the result will be the same, the answer is C.
The answer is C. The commutative property is when you can move the numbers around to get the same answer. Since 3 + 5 = 7 , 5 + 3 = 7, and they use the same numbers so you can verify that this is the commutative property.
