Using Significant Figures in Multiplication and Division. For multiplication and division, you must count the number of significant digits in each number to be multiplied or divided. Then, choose the smallest number of significant digits. This is the number of significant digits that should appear in your answer.
For multiplication or division, the rule is to count the number of significant figures in each number being multiplied or divided and then limit the significant figures in the answer to the lowest count. An example is as follows: The final answer, limited to four significant figures, is 4,094. The first digit dropped is 1, so we do not round up.
