      To add or subtract numbers expressed in scientific notation the exponents must be the same. Once the exponents are the same you add or subtract the coefficients and keep the exponents the same. Example: (8.0 x 102) + (5.4 x 103) You must first change the exponents so they are the same.

      When adding and subtracting values, find the smallest decimal place that all values have in common and are significant and that is the last significant decimal place in your answer. Add the values like normal and round to the significant decimal place. For example, 5.23 (significant to hundredths place)

      1. Significant figures. This is just the number of integers used in scientific notation. We will try to consistently use four significant figures. The more significant figures are used, the better the precision (but not accuracy) of the number. 2. Multiplying. When you have two numbers in scientific notation, it becomes very easy to do.

      6) 3.200 x 109 - four significant figures. Notice the use of scientific notation to indicate that there are two zeros which should be significant. If this number were to be written without scientific notation (3,200,000,000) the significance of those two zeros would be lost and you would - wrongly - say that there were only two significant figures.
