Roman Numbers

The Romans used several different systems for writing numbers. Sometimes they wrote numbers like this: I II III IV V and other times they used the Greek numbers. The Roman numbers were not always written the same way, either - people knew what you meant even if you did it a little differently. Here's a table showing all of the Roman numerals.

I	1		L	50
II	2		C	100
III	3		D	500
IV (or IIII)	4		M	1000
V	5
VI	6
VII	7
VIII	8
IX (or VIIII)	9
X	10

So MMIII is 2003, and XXIV is 24, and CLVII is 157. (Putting a bigger number like V after a smaller number like I means "1 less than 5" or 4).
