Roman Numbers - Ancient Rome for kids

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).
