**Mathematics**

The study of numbers, shapes, and other entities by logical means. It is divided into pure mathematics and applied mathematics, although the division is not a sharp one and the two branches are interdependent. Applied mathematics is the use of mathematics in studying natural phenomena. It includes such topics as statistics, probability, mechanics, relativity, and quantum mechanics. Pure mathematics is the study of relationships between abstract entities according to certain rules. It has various branches, including arithmetic, algebra, geometry, trigonometry, calculus, and topology.
