Unit 1 - Objective 5 - Scientific Notation
A number is said to be in scientific notation when it is written as a number whose absolute value is between 1 and 10, multiplied by a power of 10. If you shifted the decimal point n places to the right then multiply by 10n. If you shifted the decimal point n places to the left then multiply by 10-n.
To change a number from scientific notation to ordinary notation you shift the decimal point to the right if n is positive in 10n. You shift the decimal point to the left if n is negative in 10n.
