Scientific Notation - a way of expressing numbers that are too big or too small to be conveniently written.

Example of how to convert large numbers to scientific notation.

MGSE8.EE.4 MGSE8.EE.4 Add, subtract, multiply and divide numbers expressed in scientific notation, including problems where both decimal and scientific notation are used. Understand scientific notation and choose units of appropriate size for measurements of very large or very small quantities (e.g. use millimeters per year for seafloor spreading). Interpret scientific notation that has been generated by technology (e.g. calculators).
