Mathematical Markup Language is an XML based markup language
It is used to describe mathematical notations
It is designed to integrate mathematical formulas into a web site
It can be directly embedded in HTML5
Modern browser support MathML
MathML can also be interpreted by screen readers.

math → is the root element for MathML
mrow → specifies a horizontal line of elements, it groups the entire equation
mi → math identifier, and is used for variables
mo → math operator, and is used for operators like =, – etc
mfrac → a fraction. It has two child elements, numerator and denominator specified by mrow
msqrt → a square root
msup → a superscript, like exponents which has two children the base and the superscript
mn → math number, numerical literals
other elements → msub, mtable, mtr, mtd
