(2) In multiplication and division, the result should be rounded off so as to have the same number of significant figures as in the component with the least number of significant figures. For example, 3.0 (2 significant figures ) 12.60 (4 significant figures) = 37.8000 which should be rounded off to 38 (2 significant figures).
Perform multiplication first. 2 (1.008 g 4 sig figs) = 2.016 g 4 sig figs. The number with the least number of significant figures is 1.008 g; the number 2 is an exact number and therefore has an infinite number of significant figures.
5 Σεπ 2024 · Use the significant figures calculator to perform arithmetical operations (addition, subtraction, multiplication, division) and get the results rounded to the correct number of significant figures. You can also use this tool as a significant figure counter.
When multiplying or dividing, the answer must have the same number of sig fig as the least sig fig in the problem. Your answer can not be more accurate than any measurement in the problem.

The easier method for expressing uncertainty is significant figures, also known as sig figs, abbreviated sf. Significant figures provide only an approximation of uncertainty, but for all but the most precise needs, significant figures is the method of choice for measurements and calculations in science. * * * * * Pretest Answers: .
D. Rules for combined addition/subtraction and multiplication/division problems. Use the order of mathematical operations to determine which order to apply the rules for addition/subtraction (determine the number of sig figs for that step) or the rules for multiplication/division.
