Basic Rules to Write Roman Numerals

There are 4 fundamental rules that Roman numerals follow. These rules help us in writing or converting Roman numbers correctly.

• Addition Rule: When smaller numerals follow larger ones, their values are added.
  Example: VI = 5 + 1 = 6
• Subtraction Rule: When a smaller numeral comes before a larger one, it is subtracted.
  Example: IX = 9 = 10 − 1
• Repetition Rule: Symbols I, X, C, and M can be repeated up to three times.
  Example: XXX = 30
• Non-Repetition Rule: Symbols V, L, and D cannot be repeated.
  
  

Solved Examples on CX Roman Numerals

Example 1: Calculate the value of CI + IX in Roman numerals.
Solution: To find the value of CI + IX, let’s convert it first into numbers:
CI = C + I = 100 + 1 = 101  and IX = 10 – 1 = 9
CI + IX = 101 + 9
CX = 110
CI + IX = CX

Example 2: Write 110 in Roman numerals.
Solution: To write 110 in Roman numerals, we first have to expand it and then replace each number with the respective symbol as:
110 = 100 + 10
110 = C + X
Hence, 110 = CX

Example 3: Find the value of CXV – V in Roman numerals.
Solution: To find the value of CXV – V in Roman numerals, first convert it into numbers:
CXV = 100 + 10 + 5 = 115 and V = 5
CXV – V = 115 – 5
CXV – V = 110
CXV – V = CX
