Yes, numbersytems are symbolic representations of the actual numbers. We somehow all agree in the meaning of those actual numbers, probably based on how those numbers relate based on operators like +? Eg Apple + banana = pineapple

Exactly!

And it can lead to constructs like abstract algebras in which we define new sets of "numbers" and alternative definitions of "+" and "*" to create things like multi-valued logics, fuzzy logics, rings, fields, etc. for nonmonotonic reasoning, cryptography, state machine design, computer circuit design, etc.

A number need not represent a quantity. It could be an index on to a more abstract set. (But, of course, that must be clearly stated so that everyone understands how the number-symbols and operator-symbols have been overloaded with different functionality for the purposes of a given research effort or field of math).
