For one thing it could already be known. I am not an expert on Graph theory.

hi bobbym

maybe it is.but let's pretend it isn't and build up on it.

What does it mean to add to graphs here?

hi bobbym

it means just to add their polynomials to get a third polynomial and then draw a graph that is represented by that polynomial.

Yes, I know but what did that do? Why would we add them in the first place?

hi bobbym

maybe we should ask the inverse question.now that we have added the graphs what have we achieved and what purpose does this serve?

anyway,what interests me more than adding graphs is multiplying them.and i suspect that these two binary operations have something to do with drawability as well,but that's just a guess.

Okay, when you multiply the graph what does that mean?

Of course that result can be rigorously obtained, but who cares?

Combinatorics is Algebra and Algebra is Combinatorics.
