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 "x3 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
