## LaTeX on Calculemus

with 2 comments

Calculemus! is set up to display mathematical symbols using LaTeX, when viewed in Firefox* or IExplorer+MathML. (This is how I did it.) If you are contributing posts or comments here, just type your pretty LaTeX code between dollar-signs.
Example:

Enter this: To get this:
<ol><li> $\nabla (x=y)$</li><li> $\hat{x}[\nabla(x=a)]b$</li><li> $\lnot \nabla(a=a)$</li><li> $\lnot\hat{x}[\nabla(x=a)]a$</li><li> $a \neq b$</li><li> $\Delta (a\neq b)$</li></ol>
1. $\nabla (x=y)$
2. $\hat{x}[\nabla(x=a)]b$
3. $\lnot \nabla(a=a)$
4. $\lnot\hat{x}[\nabla(x=a)]a$
5. $a \neq b$
6. $\Delta (a\neq b)$

It works in the posts and the comments as well, but in the comment-writing mode it will show just the code (see the post in full-view mode for the magic).

See this page for the supported LaTeX commands, and don’t forget to check out Peter Smith‘s LaTeX for Logicians page.

* For me it looks best when viewed in Firefox, with ClearType turned on.
