AMS-LaTeXis a collection ofLaTeXdocument classes and packages developed for theAmerican Mathematical Society(AMS). Its additions to LaTeX include the typesetting of multi-line and other mathematical statements, document classes, andfontscontaining numerous mathematical symbols.

It has largely superseded the plainTeXmacro packageAMS-TeX.AMS-TeX was originally written byMichael Spivak,and was used by the AMS from 1983 to 1985.

MathJaxsupports AMS-LaTeX through extensions.

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:

${\begin{aligned}y&=(x+1)^{2}\\&=x^{2}+2x+1\end{aligned}}$

AMS-LaTeX also includes many flexible commands for formatting and numbering theorems, lemmas, etc. For example, one may use the environmenttheorem

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