LaTeX additions for the American Mathematical Society From Wikipedia, the free encyclopedia

**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.^{[1]}

It has largely superseded the plain TeX macro package **AMS-TeX**.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.^{[2]}

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:

AMS-LaTeX also includes many flexible commands for formatting and numbering theorems, lemmas, etc. For example, one may use the environment `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)Supposeare the side-lengths of a right triangle.Then.
