Mathematical Operations Using Significant Figures
side 1
Calculating experimental results usually requires a variety of mathematical operations,
such as adding, subtracting, multiplying, or dividing. Calculations also frequently use
several types of measurements, all with varying levels of accuracy. The uncertainty of the
final result must be accounted for as precisely as possible. In order to do this, scientists
have developed rules for determining the correct number of significant figures that
should be included when reporting calculated results. In general, the final reported value
should be no more precise than the least precise measurement used in the calculation
