Calculus essentially takes the fundamentals of algebra and extends them to include rates of change between quantities. The concepts are taught entirely through step-by-step example problems of increasing difficulty. It works by introducing each new concept in an easy to understand way and using example problems that are worked out step-by-step and line-by-line to completion. This lesson introduces one of the central topics in Calculus known as the integral. The integral is introduced as the opposite of the derivative and this property is used to solve several integrals to reinforce the concept. The difference between indefinite and definite integrals is presented to the student, and The Fundamental Theorem of Calculus is used to solve several definite integrals.
