Begin by reading [tour](http://math.stackexchange.com/tour), and [help](http://math.stackexchange.com/help).

Next, on this page (we being in meta), in the upper right hand corner search box, type "how to ask", and "how to answer", then read through those results as it benefits your mind. You will have much greater understanding after that.

We use MathJaX to typeset our math here, it is just $\LaTeX$ in the browser. We are, as an overall community, very kind to new users who put in effort but need help with fixing their typeset. You can start learning the rudiments of MathJax [here](https://math.meta.stackexchange.com/questions/5020/mathjax-basic-tutorial-and-quick-reference).

I, and I speak for many, warmly welcome you to our community. Asking a considerate question like this one demonstrates great character on your part. You have certainly endeared me to your cause.
