Can someone please help me?
So I think my answer above isn't very appropriate either. I think he's probably asking for the rules of elementary algebra, i.e. the kind of stuff you're allowed to do with variables that represent real numbers. But it looks like the OP has abandoned the thread, so we will probably never know.
@sponsoredwalk: Sounds like you're going for the definition of "algebra" from universal algebra, and not getting it right. (Why are you only including a binary operation?)
Since the signatures that arise in algebra often contain only function symbols, a signature
with no relation symbols is called an algebraic signature. A structure with such a signature
is also called an algebra; this should not be confused with the notion of an algebra over a
