Calculus
Calculus is the branch of mathematical science which includes limitations, issues, integrals, and infinite series. Calculus is the science of change, as geometry is the science of form and algebra is the science of work to solve equations and its applications. Calculus has extensive applications in science, economics, and technical fields; as well as solve various problems that can not be solved by basic algebra. Calculus has two main branches, the differential calculus and the integral calculus that are interconnected through the basic theorem of calculus. The calculus lesson is the gateway to another higher math lesson, which specifically studies functions and limits, which are generally called mathematical analysis.
