Which number sentence shows the commutative property of addition? 7 + 6 = 13 7 + 6 = 6 + 7 7 + (4 + 6) = (7 + 4) + 6

The commutative property in math says that numbers can be added in any order, and you will still get the same answer.

It is both 7 + 6 = 6 + 7 and 7 + (4 + 6) = (7 + 4) + 6

I would go with
7 + (4 + 6) = (7 + 4) + 6

7+6=6+7 is the correct answer because in commutative the numbers can be moved around and still get the same answer.

I’m not positive but i think it’s none of your buisness
