he Roman numeral system works by having separate symbols to represent different numbers but unlike our system there was no symbol for zero. Essentially we have 9 numbers and then add a zero on the end to denote 10s, two zeros to denote 100s and so on. the Romans simply had additional symbols to denotes 10s, 100s etc. Examples of Roman numerals and how they are worked out follows...
1 = I
2 = II (1 + 1)
3 = III (1+ 1 + 1)
4 = IV (1 before 5)
5 = V
then the system repeats...
6 = VI (5 + 1)
7 = VII (5 + 1 + 1)
8 = VIII (5 + 1 + 1 + 1)
9 = IX (1 before 10)
10 = X
Additional numerals exist for 50 (L), 100 (C), 500 (D) and 1000 (M) and they work on the same system so, for example...
XX = 20
XXX = 30
XL = 40
CCC = 300
CD = 400
CM = 900
