## anonymous one year ago Which is an example of the commutative property? A. –13 + 27 = 27 + (–13) B. –21 + (11 + 13) = (–21 + 11) + 13 C. 4(–3 + 5) = 4(–3) + 4 ∙ 5 D. –(–8 + 3) = 8 + (–3)

Wait, is this for addition or multiplication?

$$\bf{a+b=b+a}$$ that's the rule

6. airyana1114

What do you think the best answer is seeing that rule?

7. anonymous

Not really understanding it yet.

8. Mehek14

look for the answer choices where the numbers are in different order ex: $$\bf{3+5=5+3}$$

Basically whatever is on the left of the equal sign will be the same as on the right side just flipped.

Is it D?

11. airyana1114

No

12. Mehek14

no that is distributive

13. Mehek14

same for C D and C are both distributive

14. anonymous

Oh, A?

15. Mehek14

yes ^_^

16. airyana1114

Good Job :)

17. Mehek14

the numbers were flipped but when you add, you get the same answer
