business mathematics

My opinion is that mathematics is indeed a descriptive language. It is somewhat unique in this role though. The reason for this uniqueness is the fact that when people created this abstract system they wanted to use the most basic elements inherent in our reasoning, rather than just describe the observed. The result of this was a system that had very few and very basic axioms that seemed to match precisely the most basic patterns we observe in the Universe. It also meant that this system could evolve and create many patterns that appear to be greatly similar to those that we find in nature and can describe those.

What do I mean by basic elements ?
Well, one basic element of all reasoning systems we had so far is the existence of separate entities. Others are space, time, laws/relations that control the entities and possibly more.
