7.3.3 Common Markdown Extensions ↑
7.3.3.10 Superscript
As an extension to the original Markdown spec from John Gruber, superscripts are supported, in conformance with the Markdown Guide to Extended Syntax.
To create a subscript, use one caret symbol (^) before and after the characters.
So that this line…
A ^2^
… will be rendered as follows:
A 2
This line…
This apartment has an area of 100m^2^.
… is rendered like this:
This apartment has an area of 100m2.
And this expression…
y^(a+b)^
… is rendered as follows:
y(a+b)
Note that spaces should not be placed within the range of the superscript.
