How It Works
Unlike standard Roman numerals which are additive (each symbol has a fixed value), Positional Roman uses place-value notation where each position represents a power of 10.
Example: 2025
IIin thousands place (2 × 1000 = 2000)Nin hundreds place (0 × 100 = 0)IIin tens place (2 × 10 = 20)Vin ones place (5 × 1 = 5)
Result: II N II V
Why This Matters
- Scalable: Can represent any number using just 10 digit symbols
- Efficient: Enables easier arithmetic operations
- Positional: Each position represents a power of 10 (like modern decimal)
- Solves the "M limit": Standard Roman numerals struggle with very large numbers
