INTRODUCTION

Who is this website for?

Abstractmath.org is designed for people who are beginning the study of some part of abstract math. This includes:

What is abstract math?

Abstract math is my name for what is often called “higher math” or “pure math”.

Overview of the site

This website is a multiple-entry site with many cross-links.   This overview will give you a start on finding out what is on it.

The four main parts of the website

This list contains links to the head page of each of the four main parts of abstractmath.org.  These head pages explain the ideas of that part in more detail.

The languages of math

Proofs

Understanding math

Doing math

Abmath also has articles on certain mathematical topics:

 Numbers

 Sets

 Functions

 Relations

Purple prose

Many of the important ideas about mathematics in this site are summarized in

Abstractmath 2.0

Some of the articles on abstractmath, including this one, are headed Abstractmath 2.0. These articles are new or new revisions of old articles using a much more efficient system of presenting math on the web. This represents a new start on abstractmath after several years of very little change. The reasons for this and the new system are discussed in my post Writing math for the web.

This new system consists of combining the use of several well-known applications and is only new to me, not to the world.

Other things on this website

Background and Attitude:  This article shows some of the thinking behind this website.  

Diagnostic examples:  These illustrate some of the many kinds of difficulty people meet with when studying and doing abstract math.  Each example gives links to the relevant sections of the website.

Gyre&gimble:  Most new ideas I have about abstract math and language, some specifically related to abstractmath.org, are posted on this blog.

Astounding Math Stories  is a blog containing short articles that are designed to Astound you with the Weird Things that Happen in Math.  Sh!  They also have an educational purpose.

Discrete Mathematics Class Notes:   An introduction to abstract math for computing science students based on some of the ideas of abstractmath.org.
