HTML and MathML work together to bring mathematical expressions to life on web pages. This powerful combination allows developers to display complex equations with precision and clarity.

What is MathML?

MathML (Mathematical Markup Language) is an XML-based language for describing mathematical notation. It enables the representation of mathematical expressions in a structured, machine-readable format.

Integrating MathML with HTML

To use MathML within an HTML document, you need to include the MathML namespace. This is typically done in the <html> tag:

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:math="http://www.w3.org/1998/Math/MathML">

Basic MathML Syntax

MathML uses various tags to represent mathematical structures. Here's a simple example of a fraction:

<math xmlns="http://www.w3.org/1998/Math/MathML">
  <mfrac>
    <mn>1</mn>
    <mn>2</mn>
  </mfrac>
</math>

Common MathML Elements

<mi>: Identifier (variables)
<mn>: Number
<mo>: Operator
<mrow>: Group elements
<msup>: Superscript
<msub>: Subscript

Complex Example: Quadratic Formula

Here's how you can represent the quadratic formula using MathML:

<math xmlns="http://www.w3.org/1998/Math/MathML">
  <mrow>
    <mi>x</mi>
    <mo>=</mo>
    <mfrac>
      <mrow>
        <mo>−</mo>
        <mi>b</mi>
        <mo>±</mo>
        <msqrt>
          <msup>
            <mi>b</mi>
            <mn>2</mn>
          </msup>
          <mo>−</mo>
          <mn>4</mn>
          <mi>a</mi>
          <mi>c</mi>
        </msqrt>
      </mrow>
      <mrow>
        <mn>2</mn>
        <mi>a</mi>
      </mrow>
    </mfrac>
  </mrow>
</math>

Browser Support and Fallbacks

While MathML support has improved, it's not universal. Consider using JavaScript libraries like MathJax for better cross-browser compatibility. These libraries can render MathML or provide fallback options.

Best Practices

Use semantic MathML for better accessibility and machine readability.
Provide alternative text for complex equations to improve accessibility.
Test your MathML across different browsers to ensure consistent rendering.
Consider using CSS to style your MathML elements for better visual integration with your HTML content.
