Review of Scientific Notation

Scientific notation provides a place to hold the zeroes that come after a

whole number or before a fraction. The number 100,000,000 for example,

takes up a lot of room and takes time to write out, while 10

is much more

efficient.

Though we think of zero as having no value, zeroes can make a number much

bigger or smaller. Think about the difference between 10 dollars and 100

dollars. Even one zero can make a big difference in the value of the number.

In the same way, 0.1 (one-tenth) of the US military budget is much more than

0.01 (one-hundredth) of the budget.

The small number to the right of the 10 in scientific notation is called the

exponent. Note that a negative exponent indicates that the number is a

fraction (less than one).

The line below shows the equivalent values of decimal notation (the way we

write numbers usually, like "1,000 dollars") and scientific notation (10

dollars). For numbers smaller than one, the fraction is given as well.
