decimal places. Signi cant Figures When rounding to a speci ed number of signi cant gures, the process is similar to rounding to a number of decimal places. The di erence is that any leading zeros do not count as signi cant gures, so the rst n signi cant gures are the rst n digits after the rst non-zero digit.

3. A final zero or trailing zeros in the decimal portion ONLY are significant. Focus on these rules and learn them well. They will be used extensively throughout the remainder of this course. You would be well advised to do as many problems as needed to nail the concept of significant figures down tight and then do some more, just to be sure.

(4) The number "zero" presents problems in significant figures. Zeros before the first non-zero number are not significant. Zeros after numbers after the decimal place are significant. Zeros before the decimal place may or may not be significant. Each of the following numbers has three significant figures:

(the 1 has ∞ sig.figs.), therefore it is the measured quantity, the 82,500 cars, which would determine the significant figures of the conversion factor (3 sig.figs.). Significant figures for numbers calculated from other values: Multiplication and Division: The answer to a multiplication or division problem has the same number of significant

it were it wouldn't belong with these examples). It has no decimal point, so the three zeros after the “2” don't count, and the number therefore has only three significant figures. By contrast, the number “762000.” has six significant figures, since the number contains a decimal point.
