I know the third is not correct 

the second is in correct 

\

And I belive the First is incorrect 

Is this Correct Melody? 

It is the fourth one Melody \

Because it is changing up the order alittle 

Is it the Second one I belive it is.....

I just need a sec for it to load I know the communative property is 

The Commutative Property of Addition says that the order of the addends in a sum does not matter.

The Commutative Property of Multiplication says that the order of the factors in a product does not matter.

You can use the commutative properties to help you create an equivalent algebraic expression.

Rule

Commutative Property of Addition: a + b = b + a

Commutative Property of Multiplication: ab = ba

The commutative properties allow you to switch the order in a sum or product in an expression to suit your needs without changing the value of the expression. 

But the Problem is it is a real Problem not just with the letters so I dont know howyou would do a real one my lesson only taught Associtive Property....
