Operations in Scientific Notation
Addition To add numbers in scientific notation: 1) Add the constants 2) Keep the exponent the same Example: (2.1 x 105) + (3.2 x 105) = (2.1 + 3.2) x 105 = 5.3 x 105
Subtraction To subtract numbers in scientific notation: 1) Subtract the constants 2) Keep the exponents the same. Example: (7.9 x 108) (6.8 x 108) = (7.9 6.8) x 108 = 1.1 x 108
Multiplication To Multiply numbers in scientific notation: 1) Multiply the constants 2) Add the exponents Example: (5.1 x 103) ( 2.0 x 10 5) = (5.1 x 2.0) (103 x 105) = 10.2 x 108 = 1.02 x 108+1 = 1.02 x 109
Division To divide numbers in scientific notation: 1) Divide the constants 2) Subtract the exponents Example: 6.2 x 1012 = 6.2 x 1012 = 3.0 x 1010 2.0 x 102 2.0 102
