Real world system are things that science can measure, observe,
  touch and feel. Mathematics is a system that assists in
  categorizing the world in a way that humans can understand it
  better.

  Followers of Pythagoras believed in the divinity of Mathematika
  and many people are unknowingly followers of Pythagoras today.

  And no, I didn't. Self taught. All correct and incorrect
  concepts I present are my own. I don't know what evolution has
  to do with mathematics.
  Just because we invented a system doesn't mean it doesn't have
  truth value.

  There's true value in mathematics. There's truth value in
  Evolution.

  Doesn't mean they're false if I call them "maps" and not
  "reality". I don't know what you're talking about. Dude, you're
  thinking way too hard about it.
  Math didn't fall from the heavens magically.
  Men came up with the system, improved it through the years. It
  describes the world very well. So does language.
