This is my personal sandbox ;).
Some math mode tests:
[math]\displaystyle{ \sqrt{2}+\pi^{20+a_i} - \tfrac{23}{42} }[/math]
[math]\displaystyle{ \sum_{k=1}^n k = \frac{k(k+1)}{2} }[/math]
[math]\displaystyle{
\operatorname{erfc}(x) =
\frac{2}{\sqrt{\pi}} \int_x^{\infty} e^{-t^2}\,dt =
\frac{e^{-x^2}}{x\sqrt{\pi}}\sum_{n=0}^\infty (-1)^n \frac{(2n)!}{n!(2x)^{2n}}
}[/math]
