Main Question or Discussion Point
Can someone please help me?
Fredrik this is the linear and abstract algebra forum so it's a fair assumption on our partSo 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.
I can only quote it from memory but on Saturday I was looking in Suppes Introduction to@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?)
So a binary operation is simply one of the many functions that can be used. PerhapsSince 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
