Example 3. 1. 4 . 12 10 2 2. 3 . 6 10 6 3. 5 . 7 103 Multiplication and Division with Scientic Notation: Operate on the powers of 10 (using addition or subtraction according to whether you are multiplying or dividing) and the digit separately. Be sure your nal answer is in scientic notation. Example 4. 1. (6 10 2 )(4 10 5 ) = (6 4) (10 2 10 5 ) = 24 10 7 = 2 . 4 10 8 2. 4 . 2 102 8 . 4 105 = = 5 10 2 Addition and Subtraction with Scientic Notation: 1. Write numbers in ordinary notation. 2. Add or subtract. 3. Convert back to Scientic notation. Example 5. (3 10 6 ) + (5 10 2 ) (4 . 6 10 9 )(5 10 8 ) Remark If both numbers have the same power of 10, you can add or subtract the digit part of the scientic notation then convert to scientic notation if necessary. Example 6. (7 10 10 ) + (4 10 10 ) 2...
