Frequently asked questions
Scientific notation writes a number as a coefficient between 1 and 10 multiplied by a power of 10. For example, 12,345 becomes 1.2345 × 10⁴.
The exponent is how many places the decimal point moves to leave one non-zero digit in front. For 12,345 it moves 4 places, giving an exponent of 4.
It makes very large or very small numbers easier to read and compare, which is why it is common in science and engineering.
Small numbers get a negative exponent. For example, 0.0042 is 4.2 × 10⁻³.
