There are many excellent introductions to writing mathematics with LaTeX, for example Introduction to LaTeX. Below is a quick and dirty example to start with.

LaTeX is the language in which most mathematics and physics documents
are written. Mathematical symbols and equations are written in a
special markup. For example an integral sign is inserted with
`\int`

. The best way to learn LaTeX is by example. Here
is a basic LaTeX file:

\documentclass[a4paper,10pt]{article} \usepackage{amsfonts,amsthm,amsmath,amssymb} \title{Simple example} \begin{document} \maketitle \section{Quadratic equation} We want to solve $ax^2+bx+c$. The solution is \begin{equation} x= \frac{-b\pm \sqrt{b^2 -4ac}}{2a} \end{equation} \end{document}

LaTeX commands start with a back slash `\`

. Sometimes they
have an argument in curly brackets, e.g `\sqrt{b^2-4ac}`

. Most of the commands in the document above are self-explanatory.

To convert this into a readable document first save it into a file
with a `.tex`

extension, e.g. `sample.tex`

.
Then you need to process it. If you are using GNU/Linux, see
Processing LaTeX with GNU/Linux systems.
