Scientific Notation

• The first thing to learn is how to convert
  numbers back and forth between scientific
  notation and ordinary decimal notation. The
  expression "10n", where n is a whole number,
  simply means "10 raised to the nth power," or in
  other words, a number gotten by using 10 as a
  factor n times. For example

To reverse Scientific Notation, you start with an
equation such as 1.05 x 109. You start at the
decimal point and move it to the right 9
times.
1.05000000

Now you have 105,000,000.

Here is a few more examples of different types of
scientific notation

Negatives make the decimal go to the left

• 1.06 x 10-2
• So you would take the decimal and move it 2
  places to the left. That gives you .0106

6
Now you try

• 1.09 x 105
• 1.5 x 10-9
• 1.03 x 108

109,000
.0000000015
103,000,000
