Here are some formulas:

• $\alpha$
• $x^n+y^n\ne z^n$

Some inline maths: ${\sum }_{n=1}^{\mathrm{\infty }}\frac{(-1{)}^n}{n}=\ln 2$.

Some display maths:

Some random AMSTeX symbols - thanks to Robin Snader for adding these:

Note that $\hat{g}$ , $J$, and ${\gamma }_1{\gamma }_2$ all restrict to

$x_1\overline{x_2}\oplus x_2\overline{x_1}$ and that this module is linear in $x_1$ and $x_2$.
