					Notes Scientific Notation Rules for Multiplication: 2.0 X 105 * 3.5 X 10-6  Multipy the first factor: 2.0 X 3.5 = 7.0  Add the exponents of the second factor: 5 + (-6)=-1 Answer 7.0 X 10-1 Rules for Division 6.2 X 108 3.1 X 10-2

 Divide the first factor in the numerator by the first factor in the denominator. 6.2 / 3.1 = 2.0
 Subtract the exponent in the denominator from the exponent in the numerator. 8 – (-2) = 10 Answer: 2.0 X 1010 Rule for addition and subtraction: In order to add or subtract the exponents of 10 must be to the same power. Example: 3.4 X 102 + 2.3 X 105 = .0034 X 10 5 + 2.3 X 105= 2.3034 X 105 66.3 X 102 – 2.1 X 103= 6.63 X 103 – 2.1 X 103= 4.53 X 103
