Q:
# What Is Exponential Notation?

**Exponential notation simplifies calculation, especially calculation with very small or large numbers, by using positive and negative numbers to write multiples and submultiples of 10.** All numbers can be written as a multiple of 10.

Any number that has been written as an exponential notation can be converted back to a regular notation by shifting the decimal point of the numeric part a number of places equal to the value of the exponent. The number of zeros in a decimal, including the zeros to the left of the decimal point, determines the exponent. The number one written as an exponential notation is 100. A number that is raised to the zeroth power always equals one.
