Scientific Notation
Scientific notation is a way to express very large or very small numbers in the form a × 10^n, where 1 ≤ a < 10 and n is an integer. It simplifies calculations and reduces errors when working with extreme values.
Scientific Notation Rules
Large numbers: Move decimal left, positive exponent
Small numbers: Move decimal right, negative exponent
Examples:
1,500,000 = 1.5 × 10^6
0.00025 = 2.5 × 10^(-4)
Common Scientific Notation Examples
| Decimal Number | Scientific Notation | Coefficient | Exponent |
|---|---|---|---|
| 1,500,000 | 1.5 × 10⁶ | 1.5 | 6 |
| 0.00025 | 2.5 × 10⁻⁴ | 2.5 | -4 |
| 93,000,000 | 9.3 × 10⁷ | 9.3 | 7 |
| 0.0000001 | 1.0 × 10⁻⁷ | 1.0 | -7 |
| 6.02 × 10²³ | 6.02e+23 | 6.02 | 23 |

Frequently Asked Questions
What is scientific notation?
Scientific notation is a way to express very large or very small numbers in the form a × 10^n, where 1 ≤ a < 10 and n is an integer. For example, 1,500,000 = 1.5 × 10^6.
How do you convert to scientific notation?
To convert to scientific notation: 1) Move the decimal point to create a number between 1 and 10, 2) Count how many places you moved the decimal, 3) Use that count as the exponent of 10 (positive if moved left, negative if moved right).
When do you use scientific notation?
Scientific notation is used for very large numbers (like distances in space) or very small numbers (like atomic measurements). It makes calculations easier and reduces errors when working with extreme values.
