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: XL, X < L, so XL = L  X = 50  10 = 40.
 When a letter is repeated multiple 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.
