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. Roman people didn't always write numbers 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).
