Question

Are hr^2 and h^2r, wz and zw like terms?

Answer 1

zw and wz are like terms order does not matter

Answer 2

Oh. It doesn't matter if they have the same letters though?

Answer 3

ab is the same as ba
we have a property in algebra called commutative (I think that is the name of it)
basically it states that ab=ba
think of it like this 2(3)=(3)2 because when you multiply two numbers the order does not matter because they both produce the same solution
