What are Roman numerals?

A system of numerical notation used by the ancient Romans, made up of seven basic symbols used in various combinations to represent numbers.

The symbols are:

• I (1)
• V (5)
• X (10)
• L (50)
• C (100)
• D (500)
• M (1,000)

How to read Roman numerals?

1. Additive principle: The value of a Roman numeral is the sum of the values of its individual symbols. For example, XIII is 10 + 3 = 13.
2. Subtractive principle: When a smaller symbol is placed before a larger symbol, its value is subtracted from the larger symbol. For example, IV is 5 - 1 = 4.
3. Repetition: A symbol can be repeated to indicate a multiple of its value. For example, XXX is 10 + 10 + 10 = 30.

How to write Roman numerals?

1. Follow the additive principle: Write the individual symbols in order, with their values added together to form the total number.
2. Use the subtractive principle sparingly: Only use the subtractive principle when necessary to avoid confusion. For example, write IX instead of VIIII.
3. Avoid repeated symbols: Do not repeat a symbol more than three times in a row. For example, write XXXX as XL.

Examples of Roman numerals

• 1 = I

• 1,000 = M
• 49 = XLIX
• 999 = CMXCIX

Conclusion

Roman numerals are a unique and interesting system of numerical notation that has been used for centuries. While they are not as commonly used today as Arabic numerals, they still have some applications, such as in clock faces and numbering chapters in books. Understanding Roman numerals can be helpful for reading historical documents and understanding cultural references.
