The scientific notation representation of numbers is a convenient way to write both huge and small numbers. This is a quick introduction to scientific notation.

A basic idea is that any number raised to the power ( exponent ) zero is equal to one ( 1 ).

1 = 1 x 10⁰ ; 1 = meter⁰ = 1 meter/ 1 meter

This is also a fundamental part of unit cancelation in unit conversion factors.
