# Series

Series are simply suns of terms in sequences. This simple innovation uncovers a world of fascinating functions and behavior.

You're familiar with sequences and have been eager to sum them up. Well wait no longer! In this tutorial, we'll see that series are just sums of sequences and familiarize ourselves with the notation.

Whether you are computing mortgage payments or calculating the distance traveled by a bouncing ball, geometric series show up in life far more than you imagine. This tutorial will review all the important concepts and more!

Here you will learn several "tests" which determine whether certain series converge or diverge.

We've spent a lot of time thinking about whether a series converges or diverges. But, even if we can determine that a series converges, how can we figure out what it converges to? This tutorial will show techniques of estimating what a series converges to, and for determining how good our estimates are. This is super useful because most series can't be precisely evaluated (like we were able to do with infinite geometric series).
