Basic Rules of Writing Roman Numerals 

There are 4 fundamental Roman numerals 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 CXVIII Roman Numerals

Example 1: Calculate the value of CX + VIII in Roman numerals.

Solution: To find the value of CX + VIII, let’s convert it first into numbers:

• CX = C + X = 100 + 10 = 110  

• VIII = V + I + I + I = 8

Now, replace each value in expression as its numerical equivalent to find the sum:

CX + VIII = 110 + 8

CX + VIII = 118

118 in Roman numerals is CXVIII

So, CX + VIII = CXVIII

 

Example 2: Write 118 in Roman numerals.

Solution: To write 118 in Roman numerals, we first have to expand it and then replace each number with the respective symbol as:

118 = 100 + 10 + 5 + 3 

118 = C+ X + V + III

118 = CXVIII

Hence, 118 = CXVIII

 

Example 3: Find the value of CXX - II in Roman numerals.

Solution: To find the value of CXX - II in Roman numerals, first convert it into numbers: 

• CXX = 100 + 10 + 10 = 120 

• II = 2

Now, replace each each value in expression as its numerical equivalent to find the difference:

CXX - II = 120 - 2

CXX - II = 118

118 in Roman numerals is CXVIII

CXX - II = CXVIII

 

Practice Problems on CXVIII Roman Numerals

1. Write 2 Roman numerals immediately before CXVIII.

2. Covert 118 in Roman numerals.

3. Find the value of X + XVIII.

4. Subtract XII from CXXX.
