What is Scientific Notation? If we shorten a message, we must do it in a way that is useful, easy to understand or standard/universal. In Science and Mathematics, we often use abbreviations. One way we shorten Science and Math messages is using scientific notation. What is Scientific Notation? Scientific notation is a mathematical expression used to represent a decimal number between 1 and 10 multiplied by ten, so you can write large numbers using less digits.  Examples: 4000 is written as 4 x 10³ 54700 is written as 5.47 x 104 9.645 is written as 9645 x 10-3
