A few simple rules from what I remember:

* Roman numerals consist of the letters I (1), V (5), X (10), L (50), C (100), and M (1000).
* Letters to the right add that quantity, letters to the left subtract.

Thus, we get:

|I|1
|II|2
|III|3
|IV|4
|V|5
|VI|6
|VII|7
|VIII|8
|IX|9
|X|10

There's more to it, but there's probably a much better reference page out there somewhere.
