![Learning Goal:
To learn how to round an answer to the correct
number of significant figures.
Multiplication and division
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
When multiplying or dividing, the final answer is rounded to the same number of significant figures as the measured
number with the fewest significant figures.
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.
Addition and subtraction
When adding or subtracting, the final answer is rounded to the same number of digits to the right of the decimal point as
the measured number with the fewest digits to the right of the decimal point. This item does not cover measured values
without a decimal point, which may involve interpreting values with an ambiguous number of significant figures.
