What is Roman Numeral?
Roman numerals are a numeral system that originated in ancient Rome and were used throughout the Roman Empire. Unlike the modern decimal system, which uses Arabic numerals (0, 1, 2, 3, etc.), Roman numerals are based on combinations of letters from the Latin alphabet. The basic Roman numerals and their corresponding values are:
I – 1 V – 5 X – 10 L – 50 C – 100 D – 500 M – 1000
All Steps Related to Roman Numeral
Here are the steps related to Roman numerals:
- Understand the basic Roman numeral symbols and their values:
- I – 1
- V – 5
- X – 10
- L – 50
- C – 100
- D – 500
- M – 1000
- When writing a Roman numeral, start from left to right with the largest value symbol.
- If a smaller value symbol appears before a larger one, subtract its value. For example:
- IV represents 4 (5 – 1).
- IX represents 9 (10 – 1).
- XL represents 40 (50 – 10).
- XC represents 90 (100 – 10).
- CD represents 400 (500 – 100).
- CM represents 900 (1000 – 100).
- If smaller value symbols appear after a larger one, add their values. For example:
- VII represents 7 (5 + 1 + 1).
- XIII represents 13 (10 + 1 + 1 + 1).
- LXII represents 62 (50 + 10 + 1 + 1).
- Continue this process until you have represented the entire number in Roman numerals.
- When writing Roman numerals, remember to follow these rules:
- Roman numerals are written in descending order of value from left to right.
- There should not be more than three consecutive identical symbols. If you need to represent a number with more than three identical symbols, use a bar or line (known as a vinculum) above the symbol to indicate multiplication by 1000. For example, 4000 is represented as IV with a horizontal line above it: ̅IV.
