That sounds overly complicated.  If you don't feel like adding new 
tags (and with HTML 3.0 Math emphasizing presentation over 
semantics, I don't know that I'd want to see that added), there's 
always OBJECT:

<OBJECT DATA="data:text/x-minse,a*'exp(x,2)+b*x+c=0">
(Your browser doesn't support mathematical expressions.  Fortunately,
you can <a 
href="http://wheat.uwaterloo.ca/cgi-bin/kryee/nph-pmpm.cgi"> invoke 
Ping's MINSE polymediator</a> to render this equation for you.) 
</OBJECT>
