ROMAN NUMBERS

The system of Roman numerals is a numeral system originating in ancient Rome, and was adapted from Etruscan numerals. The system used in antiquity was slightly modified in the Middle Ages to produce the system we use today. It is based on certain letters which are given values as numerals:

I or i for one,

V or v for five,

X or x for ten,

L or l for fifty,

C or c for one hundred (centum),

D or d for five hundred,

M or m for one thousand (mille).

For larger numbers (five thousand and above), a bar is placed above a base numeral to indicate multiplication by 1000.
