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

By 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 ones, tens, and hundreds parts.

Step 2: Write Roman Numerals for each part.

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

Example: For the number 999.

Step 1: Break the numbers 900 + 90 + 9 = 999

Step 2: Add Roman Numerals for each part 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 900 (CM) + 90 (XC) + 9 (IX) = CMXCIX. Therefore, the Roman Numeral of 999 is CMXCIX. 

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 912.

Step 1: Start with the larger numbers. While splitting, we will get 900 and 12 The Roman Numeral of 900 is CM

Step 2: Add or subtract the smaller number If we add 12 to 900 it will become 912. The Roman Numeral of 12 is XII Therefore, the Roman Numeral of 912 is CMXII.
