<h3>What is MathML?</h3>
Mathematical Markup Language is a mathematical markup language, an application of XML for describing mathematical notations and capturing both its structure and content. It aims at integrating mathematical formulae into World Wide Web pages and other documents.
The MathML block uses MathJax to render MathML formulas in the editor and on the front end of a website. MathJax (https://www.mathjax.org/) is A JavaScript display engine for mathematics that works in all browsers.
To test a MathML block and enter a formula, for example: <code>\[x = {-b \pm \sqrt{b^2-4ac} \over 2a}\]</code>.
To test using math formulas inline, type an formula into a block of text, select it and hit the ‘M’ icon in the control bar. For example: <code>\( \cos(θ+φ)=\cos(θ)\cos(φ)−\sin(θ)\sin(φ) \)</code>. Note: if you are copying and pasting formulas into the rich text editor, switching to HTML/code editor mode is less likely to reformat your pasted formula.

MathML Block

The best way I have found to write math formulas on the web.
I just need to remember the LaTex syntax I haven't used in 15 years!

WPMathPub renders mathematical equations in WordPress using the mathpublisher rendering engine, supporting both pmath native syntax and LaTeX-style input and generating high-quality PNG images with transparent backgrounds.
Unlike MathJax-based plugins, WPMathPub performs server-side rendering, producing static equation images that display consistently across browsers and devices without requiring client-side JavaScript.
This approach provides reliable rendering for:
<ul>
<li>WordPress posts, pages, and comments</li>
<li>Cached pages</li>
<li>Environments where JavaScript rendering is not desirable</li>
<li>RSS feeds and feed aggregators <a href="https://www.biophysicslab.com/2026/04/11/wpmathpub-latex-math-in-social-networks/" rel="nofollow ugc">RSS example</a></li>
</ul>
WPMathPub extends the classic mathpublisher engine with modern WordPress integration including shortcode support, LaTeX translation, image caching, and configurable rendering options.
<h3>Mathematical Equation Rendering</h3>
Mathematical expressions can be embedded directly into WordPress content using the pmath shortcode.
Example:
<pre><code>[pmath]x^2 + y^2 = z^2[/pmath]
</code></pre>
Custom size and color:
<pre><code>[pmath size=18 color="blue"]E = mc^2[/pmath]
</code></pre>
LaTeX input with inline text:
<pre><code>This is a fraction: [pmath latex=1]\frac{a}{b}[/pmath]
</code></pre>
Expressions are rendered as PNG images using the GD and FreeType libraries and cached for efficient reuse.
<h3>Features</h3>
<ul>
<li>pmath shortcode tag math expression rendering</li>
<li>Inline text with math images using pmath shortcode tag</li>
<li>Control of math image size and color</li>
<li>LaTeX command translation (<a href="https://www.biophysicslab.com/wordpress-math-publisher-plugin/wpmathpub-syntax/" rel="nofollow ugc">Check out the complete syntax list</a>)</li>
<li>Server-side PNG equation generation</li>
<li>Gutenberg WPMathPub math block with PMath and LaTeX mode switching</li>
<li>Halo-free color rendering with alpha transparency</li>
<li>Transparent background support for dark themes</li>
<li>Minimal WordPress database footprint</li>
<li>Efficient PNG image caching</li>
<li>WordPress admin tools panel
<ul>
<li>Configurable default equation size</li>
<li>Configurable default equation color with color picker</li>
<li>Installation status display</li>
<li>PNG image cache status and control</li>
<li>Policy control for cleanup on plugin delete</li>
</ul>
</li>
</ul>
