Rules for Significant Figures
Add the values like normal and round to the significant decimal place. For example, 5.23 (significant to hundredths place) + 3.484 (significant to thousandths place) 8.714 ( 8.71. The answer is limited to the hundredths place because 5.23, so the answer is rounded to 8.72 (hundredths place). For example, 1050 (significant to tens place)

Calculating with Significant Figures. Multiply/Divide. Count the number of significant figures in each of your measurements used in the calculation. The . answer. will have as many as the . least number of significant digits. Ex. 6.2m x 10.5m = 65.1 m2 = 65 m2. Add/Subtract. After adding or subtracting, keep all digits to the left of the decimal.

The total number of significant figures in the numbers used in the calculation determines the number of sig. Figs in the answer. The number that contains the least significant figures determines how many sig. figs. should appear in the answer. (2.3)(4.612) = 10.6-76 = 10.6. 4.036 / 4.036 = 1.000.
