I can't help you wish HTML unfortunately but I can summarise the issue
in LaTeX.  

With the standard document class (article say), equations can be either
"displayed" or "inline".  Only displayed equations are numbered and then
only if you use =equation= (or =align=, =eqnarray=, etc).  $$ ... $$ is
equivalent to \[ ... \] which is essentially equivalent to the
unnumbered version of \begin{equation} (aka \begin{equation*}).

The trick would be to get the HTML exporter to apply the same processing
to \begin{equation} ... \end{equation} as it does to $$ ... $$, I guess?
