What Is MathML (Mathematical Markup Language)?

MathML (Mathematical Markup Language) is an XML-based language for describing mathematical notations and capturing both its structure and content.

The MathML specification is an open standard developed by the w3.org. See the latest version at https://www.w3.org/TR/MathML/.

Main features of MathML are:

• XML-Based Language - Can be embedded in XML documents directly and manipulated by XML tools.
• Part of HTML5 Specification - Can be embedded in HTML5 documents directly, rendered by Web browsers, and manipulated by HTML tools.
• Two Sets of Elements - 1. Presentation Markup Elements: Focuses on the presentation of an mathematical expression. 2. Content Markup Elements: Focuses on the structure of an mathematical expression.

Here is a MathML example to represent the Quadratic Formula:

<math xmlns="http://www.w3.org/1998/Math/MathML">
  <mrow>
    <mi>x</mi> <mo>=</mo>
    <mfrac>
      <mrow>
        <mrow><mo>-</mo><mi>b</mi></mrow>
        <mo>&#x00b1;</mo>
        <msqrt>
          <mrow>
            <msup><mi>b</mi><mn>2</mn></msup>
            <mo>-</mo>
            <mrow>
              <mn>4</mn><mo>&#x2062;</mo>
              <mi>a</mi><mo>&#x2062;</mo>
              <mi>c</mi>
            </mrow>
          </mrow>
        </msqrt>
      </mrow>
      <mrow>
        <mn>2</mn><mo>&#x2062;</mo>
        <mi>a</mi>
      </mrow>
    </mfrac>
  </mrow>
</math>

The above MathML structure will be rendered in Web browser as:

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$
