Understanding Decimal Numbers
The decimal system, also known as the base-10 system, is a positional number system that uses ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Each digit's position in a number represents a power of 10. As an example, in the number 77200:
- The rightmost digit (0) represents 0 × 10⁰ = 0
- The next digit (0) represents 0 × 10¹ = 0
- The next digit (2) represents 2 × 10² = 200
- The next digit (7) represents 7 × 10³ = 7000
- The leftmost digit (7) represents 7 × 10⁴ = 70000
Adding these values together, we get 70000 + 7000 + 200 + 0 + 0 = 77200. This illustrates the fundamental principle of positional notation in the decimal system. Each digit's contribution to the overall value depends on its place within the number.
