# Series

A **series** is defined as the sum of the terms of a sequence. It is one of the most powerful and useful tool in an introductory
Calculus course. It's convenient to have the perception that they are simply just an ingenious exercise in influencing
limits and in understanding convergence, but they are among the key significant methods applied in studying differential
equations, in establishing techniques of numerical analysis, in identifying new functions, in calculating the
patterns of functions, and many more.

Mastering the concept of series enables you to understand quickly the many subjects in mathematics, not only in Calculus. So, let's start studying series now!
