The rules for reading Roman numerals:
A letter repeated once or twice repeats its value that many times (XXX = 30, CC = 200, etc).
One or more letters that are placed after another letter of greater value increases the greater value by the amount of the smaller (VI = 6, LXX = 70, MCC = 1200).
A letter placed before another letter of greater value decreases the greater value by the amount of the smaller (IV = 4, XC = 90, CM = 900).
