 Evidently you use backslashes for everything (Is this a latex-specific thing, or a mathjax-specific thing?) Turns into $\left( \sum_{k=1}^n a_k b_k \right)^{\!\!2} \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$ Inline LaTeX You can use LaTeX inside of a paragraph as well by surrounding it by . The quick brown fox $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$ jumps over the lazy red dog. turns into The quick brown fox $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$ jumps over the lazy red dog. Conclusion If there's anything I'm leaving out (likely) let me know!

You are an Angel of the Lord. {O:-)} Thank you for your kindness, Xhin. We truly appreciate this.

About your first question, yes, the command \ [ ... \ ] are used in LaTeX. In fact I use it all the time. Other times I use the double dollars $you mentioned. When I want a displayed equation to be numbered I use the environment variable: \ begin{equation} .... Equation goes here ... \ end{equation} Hey that worked! Edited March 18th, 2015 by The Fly View Source Quote Report Interesting... Posted March 18th, 2015 by GHOW View Source Quote Report Oh neat, I didn't think about spacing out the backslashes. That's good! I used the  trick for the $$thing (after a little tweak to get it to render as <em></em> instead of literally nothing). Posted March 18th, 2015 by Xhin View Source Quote Report Yeah, I had to put a space after the \ since it did work otherwise! Let me test ... \pi^{-1/2}. So one dollar doesn't work. So it needs more money two dollars!$$\pi^{-1/2}$$Yup! Worked! I see you TeXed the Cauchy-Schwartz inequality! We're gonna teach the people of GT to do some TeXing here. You said it! This is gonna be TeXan land from now on! ;-) Edited March 18th, 2015 by The Fly View Source Quote Report Yeah it doesn't work with single dollar signs. And you wouldn't want it to, really..

I've got the mathjax showing up on the left now where it belongs.

When I've used other Latex supporting sites like stackexchange, single dollar signs let you do inline code, while double dollar signs gives you a separate centered paragraph. Any chance we could get that sort of inline functionality?

Also my OP was wrong about inline math. You apparently just use the backslash syntax for it.

there are two solutions to $$ax^2 + bx + c = 0$$.

Yeah inline math is supported by default really..
