What is scientific notation?
Scientific notation writes a number as a × 10n, where a is between 1 and 10. It makes very large and very small numbers easy to read and compare.
| Standard form | Scientific notation |
|---|---|
| 300,000,000 | 3 × 108 |
| 0.00042 | 4.2 × 10−4 |
| 6,020 | 6.02 × 103 |
How to convert
- Move the decimal point until one non-zero digit is left of it.
- Count how many places you moved it; that’s the exponent.
- Moving left gives a positive exponent, moving right gives a negative one.
