What are the Basic Rules to Write Roman Numerals?

  • When a bigger letter precedes a smaller letter, the letters are added. For example: MI, M > I, so MI = M + I = 1000 + 1 = 1001
  • 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 2 or 3 times, they get added. For example: III = I + I + I = 1 + 1 + 1 = 3
  • The same letter cannot be used more than three times in succession.

LXXX Roman Numerals Examples

  1. Example 1: Find the Product of Roman Numerals LXXX and XXIX.

    Solution:

    LXXX = 80 and XXIX = 20 + 9 = 29
    Now, LXXX × XXIX = 80 × 29 = 2320
    Since, MMCCCXX = 2000 + 300 + 20 = 2320
    Therefore, LXXX × XXIX = MMCCCXX

  2. Example 2: Find the Difference Between LXXX and VII.

    Solution:

    Roman Numeral LXXX is equal to 80 and VII is 7.
    Now, LXXX - VII = 80 - 7 = 73
    Since, 73 = LXXIII
    Therefore, LXXX - VII = LXXIII

  3. Example 3: Find the Sum of MDXXXVII and LXXX Roman Numerals.

    Solution:

    MDXXXVII = 1000 + 500 + 30 + 7 = 1537 and LXXX = 80
    Now, MDXXXVII + LXXX = 1537 + 80 = 1617
    Since, MDCXVII = 1000 + 600 + 10 + 7 = 1617
    Therefore, the sum of MDXXXVII and LXXX roman numerals is MDCXVII

  4. Example 4: Find the Quotient of 80 and 60.

    Solution:

    The roman numeral LXXX is 80 and LX is 60.
    Now, when we divide LXXX by LX i.e. 80 ÷ 60, the quotient is 1.
    Since, 1 = I
    Therefore, LXXX ÷ LX = I
