# AMS-LaTeX

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It has largely superseded the plain TeX macro package AMS-TeX.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.

The following code of the LaTeX2e produces the AMS-LaTeX logo (File:AMS-LaTeX.svg):

%%% -- AMS-LaTeX_logo.tex -------
\documentclass{article}
\usepackage{amsmath}

\begin{document}
\AmS-\LaTeX
\end{document}
%%% +----1----+----2----+----3---


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}
