“Truth is ever to be found in simplicity, and not in the multiplicity and confusion of things.” ~ Isaac Newton
Mathematics is the study of numbers. It is the study of topics like quantity, structure, space, probability, arithmetic, calculus, structure, space and change. Describing this word in shot, one would simply say that mathematics is a subject of calculations. We use algorithms, theories and theorems to find out a solution to a particular puzzle or calculation applying formulas of mathematics and if I talk about my personal point of view, no subject can be left spared from mathematics and every subject is directly or indirectly related with it.
