How to write formulas in html

HTML Superscript Tag <sup> is used to define a superscript text in HTML.

A Superscript text appears to be half a character above the normal character top.

Superscript Tag <sup> is used to write formulas e.g. e=mc²or 2²⁼4.

Superscript Tag is a closed tag and hence needs to be closed using the closing Superscript HTML Tag </sup>.
