TeX is a powerful typesetting system that is the current standard for creating mathematical documents. A system called LaTeX, which includes TeX along with many “macros” to make your life easier, is used by most mathematicians.

Decide whether you're going to use the department computers (Linux) or your own (Windows, Mac, or Linux). Getting LaTeX working on your computer takes two steps: (1) installing LaTeX, and (2) getting an editor. Once you've completed these two steps, download an example TeX file (see below) and try compiling the TeX file into a PDF. Congratulations, you are now a LaTeX user!

Install MacTeX, which includes TeXShop. Open a LaTeX file in TeXShop and click the “Typeset” button. You can make changes in the editing window and view the results in the PDF preview window.

Install proTeXt.

Using a terminal, change into the directory where your LaTeX file is. If your file is called myfile.tex, then run the command pdflatex myfile.tex. In the same directory should be myfile.pdf. You can make changes using any text editor (or retransfer / download your updated LaTeX file) and rerun pdflatex.

If you get a command doesn't exist error, some of the “local machines” (like the math department computers in the grab lab) don't have TeX/LaTeX installed. First, SSH into one point/round/line/tangent, cd to the right directory, and try again. If you're running Linux on your own computer at home, you might need to first install tetex.

An error message indicates invalid LaTeX. When you get a message like

! LaTeX Error: Bad math environment delimiter.
See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
l.12 \begin{displaymath}
?

Enter either q or x to get out. LaTeX suggests the error is at line 12. In reality, it may be on some line nearby.

There are many tools available for editing TeX files. Here are a few:

• TeXstudio
• Texmaker
• Overleaf – Real-time Collaborative Writing and Publishing Tools

Everything before the command \begin{document} is called the preamble. You may have noticed that some LaTeX preambles contain lines starting with \usepackage. This is how you load packages, which are even more macros that work on top of the basic LaTeX setup. For example, the diagrams package below enables easier-to-use commands to create commutative diagrams than in standard LaTeX.

Some of these packages may already be installed in your version of TeX.

Before beginning the tutorial, we present a selection of example LaTeX files.

A great place to find many examples of LaTeX source code is the arXiv. Virtually every preprint on the arXiv is typeset using LaTeX and has source code available for download from the summary page.

• A short list of the most commonly used LaTeX mathematical symbols.
• Comprehensive LaTeX Symbol List
• The TeX Users' Group (TUG) is a good place to look for all things (La)TeX. In particular, TUG maintains the Comprehensive TeX Archive Network (CTAN), which contains many files for learning about and extending the capabilities of LaTeX.
• Another popular book is George Gratzer's Math into LaTeX, the first part of which is available online. (This file contains a comprehensive introduction for getting started with LaTeX as well as well-formatted tables of special characters.)
• A popular reference, especially for those just starting to use LaTeX, is the (Not so) Short guide to Latex. It has pages of sample math codes and tables of math symbols including arrows, binary relations, and more.
