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 CCXXVIII Roman Numerals

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

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

• CCXX = C + C + X + X = 100 + 100 + 10 + 10 = 220  

• VIII = V + I + I + I = 5 + 1 + 1 + 1 = 8

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

CCXX + VIII = 220 + 8

CCXX + VIII = 228

228 in Roman numerals is CCXXVIII

So, CCXX + VIII = CCXXVIII

Example 2: Write 228 in Roman numerals.

Solution: To write 228 in Roman numerals, we first have to expand it and then replace each number with the respective symbol as:

228 = 100 + 100 + 10 + 10 + (5 + 1 + 1 + 1)

228 = C + C + X + X + (V + I + I + I)

228 = CCXXVIII

Hence, 228 = CCXXVIII

Example 3: Find the value of CCXL – XII in Roman numerals.

Solution: To find the value of CCXL – XII in Roman numerals, first convert it into numbers: 

• CCXL = 100 + 100 + 50 – 10 = 240 

• XII = 12

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

CCXL – XII = 240 – 12

240 – 12 = 228

228 in Roman numerals is CCXXVIII

CCXL – XII = CCXXVIII
