Scientific Notation (write in scientific notation)
When dealing with very big or very small numbers, it's often convenient to compress them and make them uniform. We use scientific notation to do this!
When writing in scientific notation, you move the decimal of any number to just after the first (highest) non-zero digit. You then multiply that number by a multiple of 10 to expand it back to standard form. For more on the details of how scientific notation works, see Scientific Notation (Write in Standard Form).
