2. Break and write the Roman numeral CXLIX into parts: CXLIX = C + (L - X) + (X - I)

3. Replace each Roman numeral with its value in numbers: CXLIX = 100 +  (50 - 10) + (10 - 1) = 100 + 40 + 9

Basic Rules to Write Roman Numerals

There are 4 fundamental Roman numeral rules that we need to follow for 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 = 10 - 1 = 9
  

• 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 CXLIX Roman Numerals

Example 1: Find the value of CXL + IX.

Solution: To find the value of CXL + IX, first find the value of each CXL  and IX then add them together:

• CXL = C + L + X = 100 + (50 - 10) = 140

• IX = X - I = 10 - 1 = 9

Write each addends with their respective value as:

CXL + IX =  140 + 9

CXL + IX =  149

Therefore, CXL + IX =  CXLIX

Example 2: Calculate the value of 200 - 51 in Roman numerals.

Solution: Let’s subtract 51 from 200 to get the result first and then convert the number with respective Roman numerals:

 200 - 51 = 149

 Therefore, 200 - 51 is  CXLIX Roman numerals.
