Here is the commutative law.

Which fits this description?

**You can answer that for me**

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....

You wrote this f:

Commutative Property of Multiplication: ab = ba

So there has to be one thing multiplied by another thing. Then the 2 are swapped around on the other side of the equal sign.

(Remember that a dot is a multiply sign)

So which one do you think is right?

OR which ones are you pretty sure are wrong ?

I know the third is not correct

the second is in correct

\

And I belive the First is incorrect

Is this Correct Melody?

The first one has 12a-6 on the right side. This is not (one thing) X (another thing.) So it is not right

the third one is not correct either. Why??

Which one is first thing x second thing = second thing x first thing ??

Show me how you think the forth one works

left hand side is (3*4a) - 2 What two things are multipled here.

One thing is (3*4a) the other thing is (2) there is a **minus** sign between them. NOT a** times** sign!

Don't over-think this , Nickolas!!!

Your first answer of "the second one" was correct......!!!!

Let a = 3

Let b = ( 4a - 2)

So

3*(4a - 2) = (4a - 2)*3

a*b = b*a

The commutative property of multiplication says that a*b = b*a.

**Because of this, the answer is the 2nd one.**
