Basic Rules to Interpret Roman Numerals
 When a bigger letter precedes a smaller letter, the letters are added. For example: MX, M > X, so MX = M + X = 1000 + 10 = 1010.
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: IV, I < V, so IV = V  I = 5  1 = 4.
 When a letter is repeated multiple times, they get added. For example: MM = M + M = 1000 + 1000 = 2000
 The same letter cannot be used more than three times in succession.
