Basic Rules to Write 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 CXI Roman Numerals

Example 1: Calculate the value of C + XI in Roman numerals.

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

• C = 100

• XI = 10 + 1 = 11

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

C + XI = 100 + 11

CXI = 111

111 in Roman numerals is CXI
So, C + XI = CXI\

 

Example 2: Write 111 in Roman numerals.

Solution: To write 111 in Roman numerals, we first have to expand it and then replace each number with the respective symbol as:

111 = 100 + 11

111 = C + XI

 Hence, 111 = CXI

 

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

Solution: To find the value of CXX - IX in Roman numerals, first convert both CXX and IX into numbers: 

• CXX = 100 + 10 + 10 = 120 

• IX = 10 - 1 = 9

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

CXX - IX = 120 - 9

CXX - IX = 111

111 in Roman numerals is CXI

 

Practice Problems on CXI Roman Numerals

1. Write 2 Roman numerals immediately before CXI.
