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).
