look this[tex]\[
\begin{array}{l}
 S = 1 + 2 + 4 + 6 + 8 +  \ldots  \\
 2S = 2 + 4 + 6 + 16 +  \ldots  \\
 S = 1 + 2S \\
 S - 2S = 1 \\
 S =  - 1 \\
 \end{array}
\]

How would I implement latex on my site (much simpler than BB)?
And once implemented how would I use it?

I use Ubuntu Linux.

The bbcode here simply just passes the TeX string to an external parser. Actually doing it from scratch is less trivial (search Google). There is also jsMath, which you can use.

I've used them extensively when writing math for other purposes. LaTeX is a typesetting language that only has semantic meaning, kind of like HTML has. Things like typography, layout, hyphenation, etc. is done automatically.

LaTeX is also used extensively in scientific papers, journals and the like. I guess i'm really going to have to get to grips with it at some point.

There is an editor called LyX which you can use if you don't feel like typing it in plain text. I believe they call it a WYSIWYM (what you see is what you mean) editor. I think it's available on all platforms. You can of course also just use vim and the CLI.

[tex]\sum_{n = 0}^\infty \frac{1}{n!} = \lim_{n\to\infty} \left(1+\frac{1}{n}\right)^n = e[/tex]

Testing...Hey thats cool. I think I'm gonna impress some newbies with that. Maybe get some forum points or something.
