The commutative property of addition means order does not matter, so what is the other way of adding these numbers?

1.
 + = 3 + 4
 + 1 + 6
 + 2 + 5
 7
 + 4 + 3
 None of the above
2.
 + = 1 + 5
 + 1 + 5
 + 3 + 3
 6
 + 4 + 2
 None of the above

The commutative property of addition means order does not matter, so what is the other way of adding these numbers?

 1.   If 3 + 1 = 4, then 1 + 3 = 2.   Rewrite the expression 4 + 1 using the commutative property.

 1.   Complete the equation using the commutative property. If 4 + 8 + 10 = 22, then 10 + 4 + 8 = 2.   Rewrite the expression 5 + 9 + 10 using the commutative property.

1.   Which equation(s) show the commutative property?
 6 + 8 + 9 = 6 + 9 + 8
 8 - 2 = 2 - 8
 3 + 6 = 7 + 2
 5 + 6 + 9 = 5 + 9 + 6
 none of the above
2.   Rewrite the expression 146 + 157 using the commutative property.

The commutative property of addition means order does not matter, so what is the other way of adding these numbers?

1
 + = 3 + 4
 + 1 + 6
 + 2 + 5
 7
 + 4 + 3
 None of the above
Solution
According to the commutative property of addition, 3 + 4 = 4 + 3.
2
 + = 1 + 5
 + 1 + 5
 + 3 + 3
 6
 + 4 + 2
 None of the above
Solution
According to the commutative property of addition, 1 + 5 = 5 + 1, which is none of the choices.

1If 3 + 1 = 4, then 1 + 3 =
2Rewrite the expression 4 + 1 using the commutative property.

1Complete the equation using the commutative property.
If 4 + 8 + 10 = 22, then 10 + 4 + 8 =
2Rewrite the expression 5 + 9 + 10 using the commutative property.
Solution
Any of the following expressions would be correct:
10 + 5 + 9
5 + 10 + 9
9 + 5 + 10
9 + 10 + 5
10 + 9 + 5
