Question

Which number sentence shows the commutative property of addition?

a) 3 + 0 = 3

b) 3 x 1 = 3

c) 3 + 5 = 5 + 3

d) 3 + (8 + 2) = (3 + 8) + 2

Answer 1

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.

Answer 2

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.
