Answer: 1

SOLUTION 1 :

Commutative property: r + s = s + r

You can add numbers in any order and get the same sum.

9+3 = 3+9

1) 2+(5+3) = (1+3)+6
2) 7 + 7 = 14
3) 5+2 = 2+5
4) 7 = 7 + 0

Answer: 4

SOLUTION 1 :

Identity property: d = 0 + d

Adding zero does not change a number.

7 = 7 + 0

This equation shows the identity property. Adding zero does not change the sum.

Which property of addition is shown

0 + 9 = 9

1) identity
2) associative
3) commutative

Answer: 1

SOLUTION 1 :

Associative property: (s + t) + u = s + (t + u)

You can group the addends with brackets and get the same sum.

SOLUTION 2 :

Identity property: s = 0 + s

Adding zero does not change a number.
