## Beautiful math in all browsers

A JavaScript display engine for mathematics that works in all browsers.

No more setup for readers. It just works.

## Features and Benefits

### High-quality typography

MathJax™ uses CSS with web fonts or SVG, instead of bitmap images or Flash, so equations scale with surrounding text at all zoom levels.

### Modular Input & Output

MathJax is highly modular on input and output. Use MathML, TeX, and ASCIImath as input and produce HTML+CSS, SVG, or MathML as output.

### Accessible & reusable

MathJax works with screenreaders & provides expression zoom and interactive exploration. You also can copy equations into Office, LaTeX, wikis, and other software.

### Samples

Our homepage is configured to use MathJax's CommonHTML mode with web fonts to display the equations, which produces uniform layout and typesetting across browsers. But MathJax can also be configured to use HTML-CSS (for legacy browsers), SVG, and native MathML rendering when available in a browser. You can try the various output modes using the MathJax context Menu (which you access by ctrl+clicking / alt-clicking / right-clicking an equation) or the menu below.

#### The Quadratic Formula

\[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]#### Cauchy's Integral Formula

\[f(a) = \frac{1}{2\pi i} \oint\frac{f(z)}{z-a}dz\]#### Angle Sum Formula for Cosines

\[ \cos(\theta+\phi)=\cos(\theta)\cos(\phi)−\sin(\theta)\sin(\phi) \]#### Gauss' Divergence Theorem

\[ \int_D ({\nabla\cdot} F)dV=\int_{\partial D} F\cdot ndS \]#### Curl of a Vector Field

\[ \vec{\nabla} \times \vec{F} = \left( \frac{\partial F_z}{\partial y} - \frac{\partial F_y}{\partial z} \right) \mathbf{i} + \left( \frac{\partial F_x}{\partial z} - \frac{\partial F_z}{\partial x} \right) \mathbf{j} + \left( \frac{\partial F_y}{\partial x} - \frac{\partial F_x}{\partial y} \right) \mathbf{k} \]#### Standard Deviation

\[\sigma = \sqrt{ \frac{1}{N} \sum_{i=1}^N (x_i -\mu)^2} \]#### Definition of Christoffel Symbols

\[(\nabla_X Y)^k = X^i (\nabla_i Y)^k = X^i \left( \frac{\partial Y^k}{\partial x^i} + \Gamma_{im}^k Y^m \right)\]### Accessibility and reuse.

#### Accessibility

MathJax provides a powerful set of accessibility extensions that provide navigation, exploration, and voicing on the client.

You can find more information in our introductory video on YouTube and our documentation.

### Reuse

Using the MathJax context menu, you can access the source of any mathematical expression either in MathML format, or in its original format if that was TeX or AsciiMath.

To access the MathJax menu, right-click on a math formula (if you are using Windows), or
Control-click it (if you are using a Mac) or touble-tap and hold on a touch device. In
the sub-menu “`Show Math as`

” you can choose between “`MathML Code`

” and
“`TeX commands`

” to get a pop-up that allows you to copy the math source into
another application. Try it out on the equation below!

You can also watch our screencast on YouTube of a MathJax equation being copied and pasted into a variety of applications. Note that this screencast is based on MathJax v1.1 so the menu structure is a little different in the current version.

## Documentation

### Getting Started

Whether you're a casual user, a serious author, or a professional developer, it's easy to integrate MathJax.

### A rich API

Use our extensive APIs to create interactive content, advanced authoring tools, and math-enabled web and mobile apps.

### Works everywhere

MathJax generates high-quality output on all browsers & platforms - even legacy browsers such as IE 6 (if you have to).

### Bugs, Issues, Code

We host our code, docs, and this site on GitHub. Please report issues & submit patches!

### General Support

You can ask general questions on the MathJax-Users mailing list where the entire community can chime in.

### Simple integration

Adding MathJax to your web pages is easy to do.

If you are using a Content Management System (like Wordpress, Moodle, or Drupal) to generate your web site, there may be a plugin to add MathJax to your site already, e.g., for Wordpress or Drupal. You may need to download or activate the plugin, if one is available.

If you are using specialized authoring tools, such as LaTeX or Markdown, they might integrate MathJax out of the box or have plugins, e.g., for LaTeX, Markdown, or even epub.

### Using MathJax version 3

If you write your own HTML (directly or via a template/theme engine), you can include MathJax by adding this snippet to your page:

```
<script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>
<script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js"></script>
```

Here's a pre-populated example on jsbin you can re-use.

**Note:** the configuration file `tex-mml-chtml.js`

is a great way
to test both TeX and MathML input options at once. You can find leaner
combined
components in our documentation.

If you use the snippet above, you will not need to change the version number in the
`src`

attribute every time the version of MathJax changes. If you want to always
use a specific version, then use a reference like

```
<script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>
<script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3.0.1/es5/tex-mml-chtml.js"></script>
```

Here's a pre-populated example on jsbin you can re-use.

If you are a developer who wants to integrate MathJax into your workflow, you can download a copy or fetch it from npm or Packagist and configure MathJax yourself. The source code is available from npm as well. There are example files in the MathJax Web Examples repository.

If you prefer to render server-side, MathJax version 3 makes that easy as well. There are examples in our MathJax Node Demos repository.

Jump to our v3 docs### Using MathJax version 2

Some features from version 2 are still being ported to version 3. MathJax version 2 is still available, and you can continue to use that until version 3 includes the features that you need. We will make updates to version 2 until version 3 is complete. To load MathJax version 2 into your page, use this snippet:

<script async src="https://cdn.jsdelivr.net/npm/mathjax@2/MathJax.js?config=TeX-AMS-MML_CHTML"></script>

More information is available in the version 2 documentation at the link below.

### The MathJax Sponsorship Program

The MathJax project was initiated in 2009 by Design Science, the American Mathematical Society (AMS) and the Society for Industrial and Applied Mathematics (SIAM) with the goal of creating a robust, easy-to-use, and universal solution for displaying high-quality mathematics online. From the beginning, MathJax was conceived as open-source software, on the principle that math display should be part of the common infrastructure of the web.

Providing a universal solution for online math display requires a long-term commitment. Our users need MathJax to be reliable and easy to use, now and in the future. This requires a continuous and coordinated rapid response to browser updates and bugs, keeping up with the proliferation of tablets, smartphones, and ebook readers, and a consistent approach towards new functionality and performance improvements. All of this is important to the community, and requires dedicated time, effort, and money.

Our founding sponsors have been very generous in providing funding; however, as more and
more individuals and organizations are using MathJax and its benefit to the community is
growing, its base of support grew via the Sponsorship Program. To ensure the long-term
stability of MathJax, we continuously reach out to the community and ask organizations to

## About us

MathJax is a fiscally sponsored project under the auspices of the NumFOCUS Foundation, which serves as the legal and fiscal umbrella for the MathJax project and several dozen other open-source, scientifically oriented software products.

Originally, MathJax was supported by The MathJax Consortium, a joint venture of the American Mathematical Society (AMS) and the Society for Industrial and Applied Mathematics (SIAM) to advance mathematical and scientific content on the web. We are grateful for the commitment offered by the Consortium for over 10 years, without which MathJax would not exist today.

### Core Goals

The core of the MathJax project is the development of its state-of-the-art, open source, JavaScript platform for display of mathematics. Our key design goals are:

- High-quality display of mathematics notation in all browsers.
- No special browser setup required.
- Support for LaTeX, MathML, and other equation markup directly in the HTML source.
- An extensible, modular design with a rich API for easy integration into web applications.
- Support for accessibility, copy and paste, and other rich functionality.
- Interoperability with other applications and math-aware search.
- Support for equation conversion outside a browser (e.g., preprocessing on a server).

### History

MathJax grew out of the popular jsMath project, an earlier Ajax-based math rendering system developed by Davide Cervone in 2004. In the following years, there were many significant developments relevant for web publication of mathematics: consolidation of browser support for CSS 2.1, Web Font technology, adoption of math accessibility standards, and increasing usage of XML workflows for scientific publication.

In 2009, the AMS, Design Science, and SIAM formed the MathJax Consortium to enable Cervone and others to design MathJax from the ground up as a next-generation platform, while still benefiting from the extensive real-world experience gained from jsMath. Since its initial release in 2010, MathJax has become the gold standard for mathematics on the web.

In 2019, MathJax joined the NumFOCUS family of open-source software products as a fiscally sponsored project. MathJax continues to be supported by the founding sponsors and other partners, as it joins this dynamic community.

Over the years since MathJax was first developed, new web technologies and paradigms emerged, and MathJax was not always easy to incoporate into these new approaches. In 2017, after nearly a decade of use, work on MathJax version 3 was begun, a complete rewrite of MathJax from the ground up using modern techniques. This new version integrates with current toolchains and frameworks, and can run equally well in a browser on a server, or in a stand-alone application. It should form a solid foundation for another decade of MathJax use, and its use of the Typescript language should make contributions from our user community easier to produce and incorporate into MathJax.

### The MathJax Team

The MathJax team consists of Davide Cervone and Volker Sorge. Regular contributors include Christian Lawson-Perfect, Omar Al-Ithawi, and Peter Krautzberger.
