Understanding Roman Numerals
Roman numerals are a numeral system originating in ancient Rome, using combinations of letters from the Latin alphabet. Each letter has a specific value, and these values are combined to represent different numbers.
Key Values of Roman Numerals
- I: 1
- V: 5
- X: 10
- L: 50
- C: 100
- D: 500
- M: 1000
Breaking Down CD
To understand what CD represents, we need to analyze its components:
- The letter C represents 100.
- The letter D represents 500.
In Roman numerals, when a smaller numeral appears before a larger one, you subtract the smaller value from the larger one. Thus:
- CD is formed by placing C (100) before D (500), which means you subtract 100 from 500.
Calculation
- 500 (D) - 100 (C) = 400
Therefore, the Roman numeral CD equates to 400.
Conclusion
The correct answer to what CD represents is option A: 400. Understanding the combination and placement of Roman numerals is essential for interpreting their values accurately.
