Solved Examples on CCXVIII Roman Numerals

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

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

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

• VIII = V + I + I + I = 8

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

CCX + VIII = 210 + 8

CCX + VIII = 218

218 in Roman numerals is CCXVIII

So, CCX + VIII = CCXVIII

Example 2: Write 218 in Roman numerals.

Solution: To write 218 in Roman numerals, we first have to expand it and then replace each number with the respective symbol as:

218 = 100 + 100 + 10 + 5 + 3 

218 = C + C + X + V + III

218 = CCXVIII

Hence, 218 = CCXVIII

Example 3: Find the value of CCXX – II in Roman numerals.

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

• CCXX = 100 + 100 + 10 + 10 = 220 

• II = 2

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

CCXX – II = 220 – 2

CCXX – II = 218

218 in Roman numerals is CCXVIII

CCXX – II = CCXVIII
