G -> D (which means "If G, then D")
D -> B
G
______
G -> B

That's a hugely simplistic example, and there are far more rules and logical syllogistic functions you can use, but yeah. That's basically what you're doing. Reasoning out why the world is flat in words, then showing validity by converting all the statements to symbols and then hashing it out in a proof.

Formal logic was one of my favorite classes in college
