What is smaller? 0.0000007 or 0.00000007? Goodness that is a lot of 0s! Luckily scientific notation exists to make your life simpler. Isn't it easier to compare 7 $\times$ 10-7 and 7 $\times$10-8? That would be very handy when labeling the size of this bacteria above! Scientific notation is a method of expressing numbers in an easier format to read. It is the product of a coefficient and 10 raised to a power.
