How do you know how many sig figs to use when multiplying?
The following rule applies for multiplication and division: The LEAST number of significant figures in any number of the problem determines the number of significant figures in the answer.
What is the rule for adding and subtracting sig figs?
Count the number of significant figures in the decimal portion ONLY of each number in the problem. Add or subtract in the normal fashion. Your final answer may have no more significant figures to the right of the decimal than the LEAST number of significant figures in any number in the problem.
