The HTML syntax of HTML5 allows forMathML elements to be used inside a document using <math>...</math> tags.
Most of the web browsers can display MathML tags. If your browser does not support MathML, then I would suggest you use the latest version of Firefox.
Let us see an example:
<!doctype html> <html> <head> <meta charset="UTF-8"> <title>Pythagorean theorem</title> </head> <body> <math xmlns="https://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> </body> </html>
