The document discusses significant figures and rounding in calculations involving measurement data. It explains that calculated answers should have the same number of significant figures as the measured values used. For multiplication and division, the final answer should have the same number of significant figures as the value with the fewest significant figures. For addition and subtraction, the final answer should have the same number of decimal places as the value with the fewest decimal places. Examples are provided to demonstrate rounding calculated answers to the correct number of significant figures or decimal places.
