no edit summary
This tour is not intended to be a complete introduction to group theory, or a replacement for textbook or course materials. Rather, it is intended as a supplement. To get the most from this tour, keep open your main course book or lecture notes and make sure you can ''map'' what's there on the wiki, with what you're learning in the course or from the textbook.

The tour is structured as follows.

==Part one==

This part provides some very basic, introductory definitions. We do not focus here on the example-oriented motivation for these definitions. The definitions provided are:

* [[Guided tour for beginners:Group|group]]
* [[Guided tour for beginners:Abelian group|Abelian group]]
* [[Guided tour for beginners:Trivial group|Trivial group]]
* [[Guided tour for beginners:Subgroup|Subgroup]]

Prerequisites for this part:

* An understanding of set-theoretic notation
* A basic understanding of functions between sets, unary and binary operations, and relations

The goal of this part is to:

* Provide a basic understanding of the definitions of group, subgroup, trivial group, and Abelian group

==Part two==

This part focuses on providing an understanding of how to do simple manipulations involving groups. We begin by generalizing some of the ideas involving groups, and discussing proofs involving some of the basic manipulations.

Prerequisites: Part one (or equivalent)

The goal of this part is to give comfort in simple manipulations involving groups.
