The distance from the earth to the sun is approx. 150,000,000 (1.5 x 108) km.Values such as this with many zeros are often used in scientific calculations, but entering the zeros one by one is a great deal of work and it’s easy to make mistakes.

In such a case, the numerical values are divided into mantissa and exponent portions, displayed and calculated.

<Example> W hat is the number of electronics flowing in a conductor when the electrical charge across a given cross-section is 0.32 cou- lombs. (The charge on a single electron = 1.6 x 10-19coulombs).
