Basic Rules to Interpret Roman Numerals

  • When a bigger letter precedes a smaller letter, the letters are added. For example: DX, D > X, so DX = D + X = 500 + 10 = 510.
  • When a smaller letter precedes a bigger letter, the letters are subtracted. For example: IX, I < X, so IX = X - I = 10 - 1 = 9.
  • When a letter is repeated multiple times, they get added. For example: XX = X + X = 10 + 10 = 20
  • The same letter cannot be used more than three times in succession.

Roman numerals may seem different from numbers, but they are similar. For example, 123 in roman numerals is equivalent to CXXIII. The roman numerals for numbers related to 123 are given below:

  • CXX = 100 + 20 = 120
  • CXXI = 100 + 20 + 1 = 121
  • CXXII = 100 + 20 + 2 = 122
  • CXXIII = 100 + 20 + 3 = 123
  • CXXIV = 100 + 20 + 4 = 124
  • CXXV = 100 + 20 + 5 = 125
  • CXXVI = 100 + 20 + 6 = 126
  • CXXVII = 100 + 20 + 7 = 127
  • CXXVIII = 100 + 20 + 8 = 128
  • CXXIX = 100 + 20 + 9 = 129

123 in Roman Numerals Examples

  1. Example 1: Find the value of 2000 - 123.

    Solution:

    Solving the given problem, 2000 - 123 = 1877
    To determine the value of 2000 - 123 in roman numerals, we will express 1877 in the expanded form, i.e. 1877 = 1000 + 800 + 70 + 7 = M + DCCC + LXX + VII = MDCCCLXXVII.

  2. Example 2: Find the Value of (10 - 50) + 123 in roman numerals.

    Solution:

    Solving (10 - 50) + 123 = -40 + 123 = 83. Now, we will write the answer, that is, 83 = 80 + 3 = LXXX + III = LXXXIII.

  3. Example 3: What is the remainder when CXXIII is divided by XI?

    Solution:

    XI = 11 and CXXIII = 123 in numbers.
    On dividing 123 by 11, it leaves a remainder of 2.
    Now, 2 = II
    Therefore, when CXXIII is divided by XI, the remainder is II.

  4. Example 4: Find the Difference Between 204 and 123 in Roman Numerals.

    Solution:

    Solving the given problem, 204 - 123 = 81
    To determine the value of 204 - 123 in roman numerals, we will express 81 in the expanded form, i.e., 81 = 80 + 1 = LXXX + I = LXXXI.
