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

For larger numbers, a line over the numeral indicates multiplication by 1,000. For example, X̅ = 10,000.

By Expansion Method

Through the expansion method, we break down the numbers into thousands, hundreds, tens, and ones parts, 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 19500.

Step 1: Break the numbers 10000 + 9000 + 500 = 19500

Step 2: Add Roman Numerals for each part The Roman Numeral of 10000 is X̅. The Roman Numeral of 9000 is I̅X̅. The Roman Numeral of 500 is D.

Step 3: Combine all the parts 10000 (X̅) + 9000 (I̅X̅) + 500 (D) = X̅I̅X̅D. Therefore, the Roman Numeral of 19500 is X̅I̅X̅D.

By Grouping Method

Grouping method directly from the number by combining Roman Numeral symbols. 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 12000.

Step 1: Start with the larger numbers. While splitting, we will get 10000 and 2000 The Roman Numeral of 10000 is X̅

Step 2: Add or subtract the smaller number The Roman Numeral of 2000 is MM Therefore, the Roman Numeral of 12000 is X̅MM.
