The question is: what makes a language a language? That is what makes me wonder... I mean I had a lot about calculus and logic and this stuff here. But this is just math. Not a language... A language and Math are two different things. They have quite nothing
One thing that makes them very different is: Math is exact, Languages are per se vague.
From Wikipedia: "In mathematics, logic, and computer science, a formal language is a set of finite-length words (i.e. character strings) drawn from some finite alphabet"
EDIT: That is to say, a programming language is a formal language, it is
not a natural language. The two are very different. Formal languages are exact, natural languages are not.
