AMS-LaTeX is a collection of LaTeX document classes and packages developed for the American Mathematical Society (AMS). Its additions to LaTeX include the typesetting of multi-line and other mathematical statements, document classes, and fonts containing numerous mathematical symbols.{{cite book

It has largely superseded the plain TeX macro package AMS-TeX. AMS-TeX was originally written by Michael Spivak, and was used by the AMS from 1983 to 1985.

MathJax supports AMS-LaTeX through extensions.{{Cite web|url=http://docs.mathjax.org/en/latest/tex.html#supported-latex-commands|title=MathJax TeX and LaTeX Support — MathJax 2.7 documentation|website=docs.mathjax.org|language=en|access-date=2018-08-27|archive-url=https://web.archive.org/web/20181216163219/http://docs.mathjax.org/en/latest/tex.html#supported-latex-commands|archive-date=2018-12-16|url-status=dead}}

The following code of the LaTeX2e produces the AMS-LaTeX logo:

%%% -- AMS-LaTeX_logo.tex -------

\documentclass{article}

\usepackage{amsmath}

\begin{document}

\AmS-\LaTeX

\end{document}

The package has a suite of facilities to format multi-line equations. For example, the following code,

\begin{align}

y &= (x+1)^2 \\

&= x^2+2x+1

\end{align}

causes the equals signs in the two lines to be aligned with one another, like this:

:$$

\begin{align}

y &= (x+1)^2 \\

&= x^2+2x+1

\end{align}

AMS-LaTeX also includes many flexible commands for formatting and numbering theorems, lemmas, etc. For example, one may use the environment {{samp|theorem}}

\begin{theorem}[Pythagoras] Suppose $a\leq b\leq c$ are the side-lengths of a right triangle.\\ Then $a^2+b^2=c^2$.\end{theorem}

\begin{proof}. . . \end{proof}

to generate

Theorem (Pythagoras) Suppose $a\backslash leq\; b\backslash leq\; c$ are the side-lengths of a right triangle.
Then $a^2+b^2=c^2$.
