For addition and subtraction, the result has the same number of decimal places as the measurement with the fewest decimal places. 2. For multiplication and division, the result contains the same number of significant figures as the measurement with the fewest significant figures. The rest of class we worked on the Sig Figs and Scientific Notation worksheet.
