The result contains three significant figures because the concentration of 5.25 contains three significant figures. The other numbers in the calculation, 1.5 MGD (design flow) and 8.34 (conversion factor), have no effect on the number of significant figures in the Note that if the MGD of the facility were measured at the plant rather than being

When working with significant figures where there is a mixture of operations, the rules for the individual operations do not change, but the order in which those operations are performed is important. The order in which you perform the calculations follows the “order of operations” which you may remember from algebra. That order is:

Hence a number like 26.38 would have four significant figures and 7.94 would have three. The problem comes with numbers like 0.00980 or 28.09. Rule 2: Any zeros between two significant digits are significant. Suppose you had a number like 406. By the first rule, the 4 and the 6 are significant. However, to

• Solve the operations in the parentheses first. • Keep 1 extra significant figure until the very end. • Highlight or underline the significant figures in each step. Numerator: 7.84 - 4.8 = 3.0 4 Denominator: 6 + 4.27 = 10 .27 = 10 .3 • We are subtracting and adding numbers so we need to watch decimal places .

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. (23 + 7) ÷ 10.0 = 3 (this is what your calculator spits out) In this case, your answer should have 2 significant figures, 3.0.
