Basic Rules to Interpret Roman Numerals
 When a bigger letter precedes a smaller letter, the letters are added. For example: DC, D > C, so DC = D + C = 500 + 100 = 600.
 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: CD, C < D, so CD = D  C = 500  100 = 400.
 When a letter is repeated multiple times, they get added. For example: XXX = X + X + X = 10 + 10 + 10 = 30
 The same letter cannot be used more than three times in succession.
