Calculus is a branch of mathematics that expands upon the principles used in algebra and geometry to include the idea of limits. There are two main sub-categories of calculus—differential calculus and integral calculus. Each has a different focus.
Integral calculus deals with the idea of accumulation, while differential calculus examines the rate of change. Common calculus terminology includes words such as integrals, functions and derivatives.
