Description #
MathML (Mathematical Markup Language) is an XML-based markup language designed to represent mathematical notations and structures for web content and digital documents.
History #
MathML was introduced by the W3C Math Working Group in 1998 as a standardized way to encode both the visual layout and semantic meaning of math on the web. It is maintained as part of the HTML and XML ecosystems.
Hello World Code #
<math xmlns="http://www.w3.org/1998/Math/MathML">
<mrow>
<mi>Hello</mi>
<mo>,</mo>
<mi>World</mi>
<mo>!</mo>
</mrow>
</math>How to Run #
Option 1: Online
Try it in a browser that supports MathML (e.g., Firefox):
https://mathmlcloud.org/
Option 2: Local
Create an .html file:
<!DOCTYPE html>
<html>
<body>
<math xmlns="http://www.w3.org/1998/Math/MathML">
<mrow>
<mi>Hello</mi>
<mo>,</mo>
<mi>World</mi>
<mo>!</mo>
</mrow>
</math>
</body>
</html>Then open in Firefox or Chromium-based browsers with MathML support.
Key Concepts #
- XML-based mathematical markup
- Elements like
<mi>,<mo>,<mn>for identifiers, operators, numbers - Visual and semantic math rendering
- Designed for browsers, screen readers, and printers
- Embedded natively in HTML5
- Works with LaTeX-to-MathML converters
- Compatible with assistive technologies
- Can render formulas, equations, integrals, and matrices
- Used in e-learning, academic publishing, and scientific sites
- Still evolving (now part of modern web platform efforts)
