Scientific Notation

One of the ways we use exponents in real life is when we deal with very large numbers (like the distance to the sun) or very small numbers (like the size of an electron in an atom). We often will express these numbers using scientific notation. Numbers written in scientific notation always are expressed as a decimal number between 1 and 10 multiplied by a power of 10.
