Re: [O] plus in superscript.

Hi,

$...$ may sometimes get confused with currency signs, variable names 
and whatnot.

Org-mode is sophisticated about it as long as you follow a few 
safeguards -- from the Info section 11.7.3:

     To avoid conflicts
     with currency specifications, single `$' characters are only
     recognized as math delimiters if the enclosed text contains at
     most two line breaks, is directly attached to the `$' characters
     with no whitespace in between, and if the closing `$' is followed
     by whitespace, punctuation or a dash.  For the other delimiters,
     there is no such restriction, so when in doubt, use `\(...\)' as
     inline math delimiters.

But note that MathJax, the preferred backend for math in Org's HTML 
exports, does not support $...$ by default. To configure it, see:

http://www.mathjax.org/docs/1.1/tex.html#tex-and-latex-math-delimiters

Yours,

Christian
