Leaming Goal:
To learn how to round an answer to the correct number of significant
figures.
When we report a measurement in science, we are careful to report only
digits known with certainty, plus a final digit that is recognized to be
uncertain. We call this set of digits significant figures. Often, these numbers
are used in calculations. When we use a calculator, the calculator does not
automatically account for significant figures, so we have to do so ourselves.
There are some basic rules for handling significant figures in calculations as
shown in the table and outlined to the right.
