You will need a Latex compiler. They are free to download and can be found by searching google. The Windows compatible version is called MikTex (http://miktex.org/). For samples, examples, tutorials, and templates, a good list can be found here. Here's a short reference on coding math symbols. A more complete list of Latex symbols. The main thing to know about inserting symbols in the latex file is that all math symbol codes must be entered in math mode. This simply means you must have the following syntax: $[math symbol code]$. If you forget the dollar signs, it won't compile.
