According to w3 school
The <sub> tag defines subscript text. Subscript text appears half a character below the normal line, and is sometimes rendered in a smaller font. Subscript text can be used for chemical formulas, like H2O.
The <sup> tag defines superscript text. Superscript text appears half a character above the normal line, and is sometimes rendered in a smaller font. Superscript text can be used for footnotes, like WWW[1].
example:
<p>base<sub>10</sub></p>
<p>CM<sup>2</sup></p>
check the output of that code It will help you

If u need something like the square of a number to display something like x=x*x then u can use x <sup> 2 </sup> which will make a 2 to be on top of x
But to display an equation like the formula of water u shall need H <sub>2</sub>O to display the 2 lower than the H and O.
If u are still confused then practice it
