## README for latex-amsmath bundle

### OVERVIEW

The amsmath package is an extension package for LaTeX that provides additional features to facilitate mathematical typesetting. It has been developed by the American Mathematical Society and released for general use as a service to the mathematical community. A number of smaller auxiliary packages are also distributed with the amsmath package.

Effective in 2016, maintenance of amsmath was transferred from AMS to the LaTeX3 Project; as amsmath is considered a "required" package, this centralizes control over the core LaTeX components.

### INSTALLATION AND GETTING STARTED

In order to use amsmath you need to have TeX installed first. For information on getting TeX see one of the following:

It is recommended to install a comprehensive distribution, such as TeX Live, MiKTeX for Windows, or MacTeX for Macintosh. As part of the "required" LaTeX package subset, amsmath will already be available if one of these distributions is chosen.

If you are installing amsmath manually, the most recent version will be available from the CTAN archives https://www.ctan.org/pkg/amsmath

The primary documentation for amsmath is in

- amsldoc.pdf

Additional documentation files include:

- diffs-m.txt
- subeqn.pdf
- technote.pdf
- testmath.pdf

which are included in the collection. All of these can be accessed easily with most distributions by entering `texdoc`

*filename* at the command line, or via TeXdoc Online.

### REMARKS ON THIS RELEASE

#### Version 2.17

Fixes a bug in the spacing around the closing delimiter in generalised fractions in xetex and luatex version added in release 2.16. Fixes a bug that overfull lines did not always produce warnings.

### CHANGE LOG

The file `changes.txt`

lists recent changes in reverse chronological order.

The file `diffs-m.txt`

contains information on development and changes prior to 2000.

### Reporting Bugs

If you wish to report a problem or bug in any of these packages please use the Issue Tracker for LaTeX2ε on GitHub and follow the guidelines that pop up if you press the `New issue`

button.

In particular, to check that you are really seeing a bug, please write a short, self-contained document that shows the problem. This should include the `latexbug`

package, which will warn if your test file is not suitable for one or the other reason. See the CONTRIBUTING guide for further details, or if you need to obtain the `latexbug`

package.

If the bug turns out to be with third-party software then please contact the developer, and not us!

## amsmath – AMS mathematical facilities for LaTeX

The principal package in the AMS-LaTeX distribution. It adapts for use in LaTeX most of the mathematical features found in AMS-TeX; it is highly recommended as an adjunct to serious mathematical typesetting in LaTeX.

When amsmath is loaded, AMS-LaTeX packages amsbsy (for bold symbols), amsopn (for operator names) and amstext (for text embedded in mathematics) are also loaded.

amsmath is part of the LaTeX required distribution; however, several contributed packages add still further to its appeal; examples are empheq, which provides functions for decorating and highlighting mathematics, and ntheorem, for specifying theorem (and similar) definitions.
