# Superscripts

To get an expression, exp, to appear as a superscript, you just type
`^{exp}`.

Can be used only in math mode.
Thus, for a simple expression that is part of the running text:

`x$^3$ is the third power of x`

should display as "x^{3} is the third power of x". Note that
the braces around the argument may be omitted if the superscript is
a single character.
If a symbol has both subscripts and superscripts, the order doesn't matter.
The following are equivalent:

`a_n^2` and `a^2_n`

Superscripts may have their own superscripts:

`$x^{y^{z}}$`

should display something like
z
y
x
