Are you enclosing your code with the TEX tags?

without tags: \sqrt{\frac{x}{y}}

with tags: \(\displaystyle \sqrt{\frac{x}{y}}\)

If you click the "reply with quote" or the "go advanced" you should see a \(\displaystyle \Sigma\) on the toolbar. Click that tab. You will see [noparse][/noparse] appear. Type the Latex code between them. Or else, highlight the code and then click the \(\displaystyle \Sigma\)

So [noparse]\(\displaystyle \sqrt{\frac{x}{y}}\)[/noparse] gives \(\displaystyle \sqrt{\frac{x}{y}}\)

\(\displaystyle \frac{2+sqrt{x^2+3}}{3x+2}-{x-2}\)

There's nothing to download.

To practice, use the preview function without submitting the post. The best practice is to just dive in and begin using it.
