Rules for Writing Roman Numbers

  • Rule 1: The repetition of the letters means addition.

    G4_3_RN_Rule 1

    Example: III = 1 + 1 + 1 = 3

  • Rule 2: If the letter with small value is written to the right of the letter with large value, then the values are added.

    G4_4_RN_Rule 2

    Example: LI = 50 + 1 = 51

  • Rule 3: If the letter with small value is written to the left of the letter with large value, then the smaller number is subtracted from the largest number.

    G4_5_RN_Rule 3

    Example: IX = 10 – 1 = 9

  • Rule 4: The letter I and X can be repeated only thrice.

    Example: VIIII or XXXX has no meaning.
