*Here, you find my whole video series about Algebra in the correct order and I also help you with some text around the videos. If you have any questions, you can contact me and ask anything. However, without further ado let’s start:*

#### Part 1 - Introduction

**Algebra** is a video series I started for everyone who is interested in the basics of algebra as a mathematical field. It generalises a lot of ideas from my Start Learning Mathematics series and puts them into a more abstract setting. This is not only interesting from a pure mathematical point of view but we also find a lot of applications for these concepts. The power of describing them all under a single definition is what makes algebra so useful for a lot of different parts in mathematics.

With this you now know the topics that we will discuss in this series. Some important bullet points are **groups**, **rings**, **fields** and **vector spaces**. In order to describe these things, we need to generalise a lot from the constructions of number sets. Let’s immediately start with most basic structure.

#### Part 2 - Semigroups

#### Part 3 - Identities and Inverses

After learning what a semigroup is, we can start to disguish special elements in it. The first one is a so-called **neutral** element.
