Roman Numerals rely on specific symbols, and it has rules of addition and subtraction. The basic symbols in Roman Numerals are: I = 1 V = 5 X = 10 L = 50 C = 100 D = 500 M = 1000 Using the above symbols, we can combine the Roman Numerals for the numbers easily.

There are two basic methods of writing Roman Numerals, they are

  • By Expansion Method
     
  • By Grouping Method

By Expansion Method

Through the expansion method, we break down the numbers into thousands, hundreds, tens, and ones parts and then convert them into numerals.

Step 1: Break the numbers into thousands, hundreds, tens, and ones parts.

Step 2: Write Roman Numerals for each part.

Step 3: Combine all the parts to get the numerals.

Example: For the number 3999.

Step 1: Break the numbers 3000 + 900 + 90 + 9 = 3999

Step 2: Add Roman Numerals for each part The Roman Numeral of 3000 is MMM. The Roman Numeral of 900 is CM. The Roman Numeral of 90 is XC. The Roman Numeral of 9 is IX.

Step 3: Combine all the parts 3000 (MMM) + 900 (CM) + 90 (XC) + 9 (IX) = MMMCMXCIX. Therefore, the Roman Numeral of 3999 is MMMCMXCIX. 

By Grouping Method

Grouping method directly from the number by combining Roman Numeral symbols directly. It uses addition and subtraction rules.

Step 1: Start writing numerals for the largest number.

Step 2: Smaller numbers are either getting added or subtracted.

Following the rule of adding and subtraction is mandatory.

Addition: smaller numeral after the larger numeral.

Subtraction: smaller numeral before the large numeral.

Example: For the number 1200.

Step 1: Start with the larger numbers. While splitting, we will get 1000 and 200 The Roman Numeral of 1000 is M

Step 2: Add or subtract the smaller number If we add 200 to 1000 it will become 1200. The Roman Numeral of 200 is CC Therefore, the Roman Numeral of 1200 is MCC.
