How to write superscript and subscript in markdown

In this post, we will learn how to write superscripts and subscripts in markdown.

There is no native support for superscript (sup) and subscript (sub) in markdown.

However, if you are using a markdown compiler to render the content as HTML then we can use the <sub> tag for subscript and <sup> for superscript.

Let's see with an example.
