What is MathML in Html5?

The MathML is a markup language used to describe the mathematical notation in the HTML page. It captures both the structure and the content of the mathematical notation. It enables the mathematics to be served, received, and processed on the World Wide Web.

<math xmlns = "http://www.w3.org/1998/Math/MathML">
         <mrow>
            <msup><mi>a</mi><mn>2</mn></msup>
            <mo>+</mo>
            <msup><mi>b</mi><mn>2</mn></msup>
            <mo> = </mo>		
            <msup><mi>c</mi><mn>2</mn></msup>
         </mrow>		
</math>

The above HTML code is described using a MathML markup language, and it produces the result a2 + b2 = c2.
