Scientific notation is used to compress large numbers into smaller numbers. In order to write a number in scientific notation, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10. An examples of 100 expressed in scientific notation is 1 x 10².

In order to determine the difference in the length of the great wall of China and the Panama Canal, divide the length of the Great wall of China by the length of the Panama Canal.

(1 x $10^{4}$) ÷ (5 x $10^{1}$)

(1/5) x $10^{4 - 1}$

0.2 x $10^{3}$

2 x $10^{3 - 1}$

2 x10² = 200
