Scientific Notation

It has 14 zeroes. 100,000,000,000,000. This is 100 trillion.

6.157 x 10-1

Scientific notation is a way to represent very large or very small numbers.

Developments in science allow us to investigate the universe as well as the microcosm: both these involve very large and/or small numbers. Furthermore, outside of scientific there are numbers such as population counts, the value of international trade, the US budget deficit, China's currency surplus whose use is considerably simplified by using scientific notation.

9.1*108

This means multiply the base times itself as many times as the exponents says.

Ex: 4 x 4 x 4 =64

4 to the power of 3 = 64
