LaTeX (in addition to being a kewl material) is also a text editing program (Like Microsoft Word). LaTeX allows you to write mathematics so that they look nice. Here are some examples that you can cut, paste and modify for your own uses.

Here is a fraction: $\frac{a}{b}$

Here is an exponent: xy

Here is a sub-scirpt: x1

Here is an upper case greek letter: Σ

Here is a lower case greek letter: σ

Here are some miscellaneous symbols:

$\times$

$\in$

$\int$

Here is something you might normally see: $p(x)=\frac{1}{\sqrt{2\pi\sigma^2}}e^{-\frac{(x-\mu)^2}{2\sigma^{2}}}$

f(x) & = (a+b)^2 \\
& = a^2+2ab+b^2 \\
