comment Is there a general operator symbol?
I hope it will be understood. I'm implementing arithmetic functionality like $((a # b)) that my program can evaluate according to a grammar.

comment Do you know which book this is?
@Benedict I was looking for a 2nd book in logic so I emailed the author Graeme Forbes who kindly responded with a recommendation for something that I would like. I like the historical notes in the "beta book" which has a chapter on math history. I can try and email the community in logic. The background is that I took I university course in logic and I want to "dig deeper" and know more modern logic.

"Symbolic Logic" by Graeme Forbes is very good.

comment Are all algebras groups?
My background is a course in discrete math (where the Norman Biggs book was used) and a course in logic where Graeme Forbes Symbolic Logic was used. I want to learn more lika that but I don't know exactly what I'm looking for. I also took all other undergraduate math courses and passed them (analysis and numerical methods) but my interests were discrete mathematics and symbolic logic with exactly those books. If I enjoyed those 2 books, can you recommend me more reading? I'm currently reading Peter Cameron's combinatorics book and David Wunsch's complex analysis to teach myself some more.

comment Are all algebras groups?
I can recognize boolean algebra but I can't formally define it. The similarity I was thinking of was of a set with operands and operators similarly to how you "define" the complex plan with the symbol something that looked like: `ℂ: {x,y .... ´ and I was wondering if I can define a mathematical system using mathematics rather than just use the system, since I am only a user of Boolean algebra, I don't know what it is.

comment Are all algebras groups?
Thank you for a very good answer. IIUC any group is an algebra but not all groups are algebras. Is boolean algebra a field? It seems the definition is somewhat similar to a field (for instance the field "" is the complex set with functions) or do we know that boolean algebra is not a field?

comment Are all algebras groups?
@JohnDouma I think that the elements {0,1} with the + operation (meaning "or") (or the `NAND´ operation for a functionally complete algebra) then I could google and find articles that say that boolean algebra is a group. If it is, then it is a good example of a group but I never saw it used as an example of a group before, but it seems like a good example to show that a group can define "A mathematic" or "an algebra" so that we know what we mean with the word "algebra".
