Roman Numerals rely on specific symbols with rules for 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 Roman Numerals for numbers easily.

There are two basic methods of writing Roman Numerals:
1. By Expansion Method
2. By Grouping Method

1. By Expansion Method
In this method, we break down numbers into thousands, hundreds, tens, and ones, then convert them into numerals.

Step 1: Break the numbers into thousands, hundreds, tens, and ones.
Step 2: Write Roman Numerals for each part.
Step 3: Combine all parts to get the numerals.

Example: For the number 1499

Step 1: Break the number
1000 + 400 + 90 + 9 = 1499

Step 2: Add Roman Numerals for each part

  • The Roman Numeral of 1000 is M

  • The Roman Numeral of 400 is CD

  • The Roman Numeral of 90 is XC

  • The Roman Numeral of 9 is IX

Step 3: Combine all parts
1000 (M) + 400 (CD) + 90 (XC) + 9 (IX) = MCDXCIX

Therefore, the Roman Numeral for 1499 is MCDXCIX.

2. By Grouping Method
This method involves combining Roman Numeral symbols directly, using addition and subtraction rules.

Step 1: Start writing numerals for the largest number.
Step 2: Smaller numbers are either added or subtracted.
Following the addition and subtraction rules is crucial.

  • Addition: smaller numeral after the larger numeral

  • Subtraction: smaller numeral before the larger numeral

Example: For the number 1012

Step 1: Start with the larger numbers
While splitting, we get 1000 and 10 and 2

  • The Roman Numeral of 1000 is M

Step 2: Add the smaller numbers

  • The Roman Numeral of 10 is X

  • The Roman Numeral of 2 is II

Therefore, the Roman Numeral for 1012 is MXII.
