I wanted to put a bar over my variable such as not(x) and also some set symbols in my web page? How do I incorporate that in my html page.

A:
For the set symbols, you ought to use unicode HTML entities.
For the line over a variable (p), I'd rather use an alternate symbol for not, such as:
¬p (¬p)
You may also, as a commenter pointed out, use the combining diacritical unicode HTML entity like so:
p̅ (p̅)
Lastly, you may use one of the CSS methods provided.

Those are great for the symbols but how about the bar?

Good point, I like that better, too.

For a bar you could use the combining diacritic 0x0305 (see http://unicode.org/charts/PDF/U0300.pdf)

Very cool Paul; I didn't know about this. Added to my answer.

FWIW, that diacritic doesn't work in Google Chrome.

@Dominic - for what it's worth, I'm looking at it right now in Google Chrome.

I'd rather track down a tool designed to enter mathematical symbols and then use straight Unicode rather than entities. It will result in more readable source code.
