Strategies
Order of operations is useful for expansion, but knowledge and familiarity with scientific notation is really key.
 * 1) Many calculators have a scientific notation mode that can be used to increase accuracy and speed on this problem.
 * 2) The numbers used are controlled so that there is no need for rounding. Therefore it can be good practice for practice multiplying and dividing decimals and basic exponent rules.

Real-life applications

 * 1) Scientific notation has many applications in the sciences.
 * 2) Scientific notation is useful for representing very large or very small quantities.
