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:

  • Expansion Method
     
  • Grouping Method

Expansion Method

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

Step 1: Break the numbers into 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 899.

Step 1: Break the numbers 800 + 90 + 9 = 899

Step 2: Add Roman Numerals for each part The Roman Numeral of 800 is DCCC. The Roman Numeral of 90 is XC. The Roman Numeral of 9 is IX.

Step 3: Combine all the parts 800 (DCCC) + 90 (XC) + 9 (IX) = DCCCXCIX. Therefore, the Roman Numeral of 899 is DCCCXCIX.

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 812.

Step 1: Start with the larger numbers. While splitting, we will get 800, 10, and 2 The Roman Numeral of 800 is DCCC

Step 2: Add or subtract the smaller number If we add 10 and 2 to 800, it will become 812. The Roman Numeral of 10 is X The Roman Numeral of 2 is II

Therefore, the Roman Numeral of 812 is DCCCXII.
