Given: CCXVII Roman numeral
Symbols Used: C = 100, X = 10, V = 5 and I = 1

Step-by-Step Process

1. Write each symbol according to its value: CCXVII = C + C + X + V + I + I.

2. Replace them with respective numbers and add the values together: 

100 + 100 + 10 + 5 + 1 + 1 = 217

Hence, CCXVII = 217 in numbers.

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 CCXVII Roman Numerals

Example 1: Calculate the value of CCX + VII in Roman numerals.

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

• CCX = C + C + X = 100 + 100 + 10 = 210  

• VII = V + I + I = 5 + 1 + 1 = 7

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

CCX + VII = 210 + 7

CCX + VII = 217

217 in Roman numerals is CCXVII

So, CCX + VII = CCXVII

Example 2: Write 217 in Roman numerals.

Solution: To write 217 in Roman numerals, we first have to expand it and then replace each number with the respective symbol as:

217 = 100 + 100 + 10 + (5 + 1 + 1)

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

217 = CCXVII

Hence, 217 = CCXVII

Example 3: Find the value of CCXXX – XIII in Roman numerals.

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

• CCXXX = 100 + 100 + 10 + 10 + 10 = 230 

• XIII = 13

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

CCXXX – XIII = 230 – 13

230 – 13 = 217

217 in Roman numerals is CCXVII

CCXXX – XIII = CCXVII
