$$There \hspace{3} has \hspace{3} to \hspace{3} be \hspace{3} a \hspace{3} better \hspace{3} way \hspace{3} of \hspace{3} doing \hspace{3} spaces \hspace{3} than \hspace{3} this.$$
$$\mbox{Never mind, found one. You use an "mbox" function.}$$
$$You \ can \ also \ use \ a \ single \ backslash \ for \ a \ space. \\ And \ a \ double \ backslash \ for \ a \ linebreak \ if \ you \ don't \ want \ to \ use \ the \ mbox \ function.$$
$$\fbox{\mbox{You can also make your text framed by using an "fbox", like this.}}$$
Hope all that helps someone.

This thread is linked in the subforum FAQ, but the FAQ isn't stickied any more (what happened?)
Perhaps this thread could be stickied on its own?
I don't think the Alpha rules threads are used any more, so they could maybe be unstickied if the top area is feels cluttered.
Anyway... having some difficulties with formatting. According to the tutorial page, this:
, but instead, I get:
$$\displaystyle f(x)=\int_{-\infty}^x e^{-t^2}dt$$
Not quite the same... see the position of the integral bounds?
The \displaytyle tag seems to do nothing.
It's not a big problem, but it makes this look a bit clunky:
$$\begin{align}
\frac{25x^2}{9}+y^2 &= 25 \\
(dc')^2 &= (dx)^2 + (\frac{dy}{\gamma})^2 \\
c' &= 4\int_{x=0}^{x=3}dc'
\end{align}$$
btw... to align equations like that, do this:
The double backslashes mark a new line, and the ampersands tell it where to align each line.

Got it. The details of where the limits go seem to be in the details of the implementation, but \displaystyle is the default style which is why it doesn't seem to do anything.
To explicitly dictate where the bounds or limits go, put \limits or \nolimits immediately after the \int, \sum, or whatever:
\int\limits_0^1 gives: $$\int\limits_0^1$$
\int\nolimits_0^1 gives: $$\int\nolimits_0^1$$

Math is my favorite subject. I love to read this subject.
Fun fact!
You can make simple diagrams in tex using the \picture tag.
In a picture tag, you can place any tex element at a specific location, and draw lines and circles/ellipses/arcs.
Check the picture section of the mimetex manual

$$\\frac{\alpha ^e \infty ^{1/\mu }}{\frac{\pi }{e}}\leq \int_{\psi }^{\sigma } \zeta \, d\gamma$$
$$\Large \frac{\alpha ^e \infty ^{1/\mu }}{\frac{\pi }{e}}\leq \int_{\psi }^{\sigma } \zeta \, d\gamma$$
Makes perfect sense!

Problem:
The forum software adds an untyped space after 50 consecutive non-whitespace characters starting with a backslash (except in
$$\lambda\lambda\lambda\lambda\lambda\lambda\lambda\lambda\lambda\lambda\lambda$$
Solution: Add whitespace.
