RULE #3: To add/subtract in scientific notation, the exponents must first be the same. Example: (3.0 x 10 2 ) + (6.4 x 10 3 ); since 6.4 x 10 3 is equal to 64. x 10 2 . Now add. (3.0 x 10 2 ) + (64. x 10 2 ) 67.0 x 10 2 = 6.70 x 10 3 = 6.7 x 10 3 67.0 x 10 2 is mathematically correct, but a number in standard scientific notation can only have one number to the left of the decimal, so the decimal is moved to the left one place and one is added to the exponent. Following the rules for significant figures, the answer becomes 6.7 x 10 3 . RULE #4: To multiply, find the product of the numbers, then add the exponents. Example: (2.4 x 10 2 ) (5.5 x 10 –4 ) = ? [2.4 x 5.5 = 13.2]; [2 + -4 = -2], so (2.4 x 10 2 ) (5.5 x 10 –4 ) = 13.2 x 10 –2 = 1.3 x 10 – 1 RULE #5: To divide, find the quotient of the number and subtract the exponents. Example: (3.3 x 10 – 6 ) / (9.1 x 10 – 8 ) = ? [3.3 / 9.1 = .36]; [-6 – (-8) = 2], so (3.3 x 10 – 6 ) / (9.1 x 10 – 8 ) = .36 x 10 2 = 3.6 x 10 1 18
