You are misunderstanding my point. Mathematics is not related to the natural world at all. 1 plus 1 will equal 2 regardless of whether there is a universe to experience it. It turns out certain types of math are useful to us, it doesn't mean that all types are. For example, infinite numbers exist, but the natural world cannot have an infinite or infinitessimal amount of things, there are upper and lower limits. Does that mean infinities don't exist? Of course not.
