What are the Basic Rules to Write Roman Numerals?
 When a bigger letter precedes a smaller letter, the letters are added. For example: XI, X > I, so XI = X + I = 10 + 1 = 11

 When a letter is repeated 2 or 3 times, they get added. For example: II = I + I = 1 + 1 = 2
 The same letter cannot be used more than three times in succession.
