Scientific notation refers to the system of reporting numbers as a decimal, with an established number of significant figures and use of exponentials of ten. Under this system, the number 31,250 would be 3.125 x 10^{4}

The number 1,230,000 in scientific notation is 1.23 x 10^{6} .

- The best system is to have only one digit on the left of the decimal point. You must add zeroes to provide the right number of significant figures.
- Note that 100 is 1 x 10
^{2}, but 100.0 is 1.000 x 10^{2}, because of the number of significant figures - An easy way to write exponentials on a computer is with 'E'. e.g. 2.0 x 10
^{-3}may be written as 2.0 x 10E-3
