Scientific notation is a way to express numbers in a form that makes numbers that are too small or too large more convenient to write and perform calculations with. It is commonly used in mathematics, engineering, and science, as it can help simplify arithmetic operations. In scientific notation, numbers are written as a base, b, referred to as the significand, multiplied by 10 raised to an integer exponent, n, which is referred to as the order of magnitude:
Below are some examples of numbers written in decimal notation compared to scientific notation:
| Decimal notation | Scientific notation |
|---|---|
| 5 | 5 × 100 |
| 700 | 7 × 102 |
| 1,000,000 | 1 × 106 |
| 0.0004212 | 4.212 × 10-4 |
| -5,000,000,000 | -5 × 109 |
