I am wondering if you have any suggestions for a way to display a Superscript within an <A> tag without having the Anchor's underline also superscripted.

Here's what I have:
<a href="#">Brad is testing x+x<SUP>y+x+4</SUP> to calculate</A>
What you will see on at least IE is that the Anchor underline actually breaks at the Superscript and underlines at the higher superscript text. It looks horrible.

The clients style prefers an underline, so I can't remove the Anchor's Text Decoration..

I have tried a couple of different things in CSS with Vertical-Align and Relative Positioning.

Any other ideas?
