Poll

To create an expression that is equivalent to the given expression, would you choose

A or B?

• A

• B

Poll

Mrs. Wilson says that another way to write an equivalent expression would be

$$y+3x-3$$  ...

Is she correct? Why?

• No, because x always comes before y in expressions.

• Yes, because addition is commutative, so order isn't important
