Intro to Scientific Notation

Scientific Notation

Just as exponents are a shorthand method representing multiplication, scientific notation is a shorthand method for representing vary

large (distance from Earth to the Sun) and very small (width of an atom) numbers.

As with exponents, very specific rules apply to their proper use. Unlike exponents, the rules are

few and straightforward.
