We've added support for LaTeX, a form of markup that will allow the use of logic and math symbols in posts. For example,
Math notation: \(\int_0^\infty f(x) dx\)
Logic notation: \(\forall x \, (x \rightarrow y) \rightarrow \exists y \, ( \lnot y \rightarrow \lnot x)\)
You can also create equations centered in a post on their own line: $$ \texttt{Carleas} \equiv \texttt{marginally effective} $$
To invoke the interpreter, surround LaTeX code with either double dollar signs (for centered equtaions): $$ your Latex here $$,
Or for inline equations, use parentheses preceded by a backslash: \( your Latex here \)
Click 'Quote' on this post, or on fuse's post here, to see some examples of how equations are formatted.
There are plenty of LaTeX tutorials out there, but if you find any you like please recommend them below.
