commutativity (i.e. can be switched around, Fr. commutateur=switch)

Commutative Property of Addition ?
I did read it Im just making sure if I'm correct. 
Is that the right answer to the question?

Yes. MathMate told you the answer 10 minutes ago.

Yes, you answer is correct.
Your answer is more specific than mine. It restricts the operation to addition, while commutativity applies also to some other operators such as multiplication. 
Ok
Thank You!!!
PS: I'll soon post math homework corrects (just 4 questions). I want to make sure if there any grammar mistakes and correct.
