Scientific notation
6.3 × 10^6

Scientific notation keeps exactly one nonzero digit before the decimal point — useful for very large or very small numbers where standard form gets unwieldy.

A worked example

6,300,000 in scientific notation is 6.3 × 10⁶.

Frequently asked questions

What counts as 'proper' scientific notation?

Exactly one nonzero digit before the decimal point — 6.3 × 10⁶ is proper notation for 6,300,000; 63 × 10⁵ represents the same value but isn't in standard scientific notation form.

Why use scientific notation at all?

It keeps very large or very small numbers compact and makes it easy to compare magnitudes at a glance — spotting that two numbers differ by a factor of 1000 is much easier comparing exponents than counting zeros.
