**Calculus**(Latin, calculus, a small stone used for counting) is a branch of mathematics focused on limits, functions, derivatives, integrals, and infinite series. This subject constitutes a major part of modern mathematics education. It has two major branches, differential calculus and integral calculus, which are related by the fundamental theorem of calculus.

**Calculus**is the study of change, in the same way that geometry is the study of shape and algebra is the study of operations and their application to solving equations. A course in

**calculus**is a gateway to other, more advanced courses in mathematics devoted to the study of functions and limits, broadly called mathematical analysis.

**Calculus**has widespread applications in science, economics, and engineering and can solve many problems for which algebra alone is insufficient.

Historically,

**calculus**was called "the calculus of infinitesimals", or "infinitesimal calculus". More generally,

**calculus**(plural calculi) refers to any method or system of calculation guided by the symbolic manipulation of expressions. Some examples of other well-known calculi are propositional calculus, variational calculus, lambda calculus, pi calculus, and join calculus. Wikipedia - Caculus
