Question
Roman Numbers. The Roman Number System has seven digits as follows:
I 1
V 5
X 10
L 50
C 100
D 500
M 1000
Numbers are formed according to the following rules:
Only numbers up to 3999 are represented.
As in decimal system, the thousands, hundreds, tens, and ones are expressed separately.
3. The numbers 1 to 9 are expressed as shown. As you can see, an I preceding a V or X is subtracted from the value, and you can never have more than three I’s in a row.
I II III IV V VI VII VIII IX
Tens and hundreds are done the same way, except that letters X, L, C, D, M are used instead of letters I, V, X.
