Welcome to the sandbox, a location to test your newfound wiki-editing abilities.

Please note that all contributions here may be deleted periodically and without warning.

In the computer world, a sandbox is a place to test and experiment -- essentially, it's a place to play.

This is the AoPSWiki Sandbox. Feel free to experiment here.

Warning: anything you place here is subject to deletion without notice.

If anybody knows how to embed XML tags in a Wiki page so that they don't display, but are still there, please post here.

$\mathrm{Test\;of\;mathrm}$ I am also testing dollars signs: $x+3=5$ $5+3=x$ Testing dollar signs $x^2 + 3 = 4$

Testing multiple dollar signs: $r^2+2 = 7$ and then, $r^3-2 = 9$

$$$$ $x^2 + 3 = 4$

Dollar signs. $\dfrac{y}{r}=\sin \theta$ $\frac{m}{n}$ $cheesecake$ LaTeX didn't show up in the previews because the last } was missing.

$\frac{\sqrt{b^2-4aq}}{2\pi+3\pi+4\pi}$
