Roman numerals are expressed by letters of the alphabet:
I=1; V=5; X=10; L=50; C=100; D=500; M=1000
There are four basic principles for reading and writing Roman numerals:
- A letter repeats its value that many times (XXX = 30, CC = 200, etc.). A letter can only be repeated three times.
- If one or more letters are placed after another letter of greater value, add that amount.
VI = 6 (5 + 1 = 6)
LXX = 70 (50 + 10 + 10 = 70)
MCC = 1200 (1000 + 100 + 100 = 1200)
