A way of writing numbers as a value between 1 and 10 multiplied by a power of 10, like 3.5 × 10^6.
It simplifies writing and comparing very large or very small numbers.
It indicates a small decimal number, like 10^-3 = 0.001.
Zero is typically just written as 0, since scientific notation doesn't apply meaningfully to it.
Similar but different - engineering notation restricts exponents to multiples of 3.
