What are the Basic Rules to Write Roman Numerals?

• When a bigger letter precedes a smaller letter, the letters are added. For example: LI, L > I, so LI = L + I = 50 + 1 = 51

• When a letter is repeated 2 or 3 times, they get added. For example: MMM = M + M + M = 1000 + 1000 + 1000 = 3000
• The same letter cannot be used more than three times in succession.
