Basic Rules of Writing Roman Numerals

There are 4 fundamental rules that Roman numerals follow. These rules help us in writing or converting Roman numbers correctly.

• Subtraction Rule: When a smaller numeral comes before a larger one, it is subtracted.
  Example: IX = 10 - 1 = 9

Solved Examples on CCX Roman Numerals

Example 1: Calculate the value of 200 +10 in Roman numerals.

Solution: Let’s add 200 to 10 to get the result first and then convert the number with respective Roman numerals:

200 + 10 = 210

In Roman numerals, 210 = CCX

Example 2: Find the value of CC + XX in Roman numerals.

Solution: CC = 200 and XX = 20

CC + XX = 200 + 20

CC + XX = CCXX

Example 3: Determine the value of CCXIII - X.

Solution: To determine the value of CCXIII - X, we need to first convert CCXIII and X into numbers:

CCXIII = 213 and X =10

213 - 10 = 203 

203 is represented by CCIII in Roman numerals 

Therefore,  CCXIII - X = CCIII
