For exponents, the number of sig figs is the same as in the mantissa. For example 101.23 = 17 or 1.7 x 101, which has 2 sig figs because there are 2 sig figs in the mantissa (.23). 7. For multiple calculations, compute the number of significant digits to retain in the

Rules for Reporting Significant Figures. 1. Nonzero digits always count as significant figures . 2. Zeros are what mix people up. There are three situations in which they can occur. leading zeros precede all nonzero digits and are never significant (i.e., 0.000182 has three sign. figs.)

Many people get confused by zeroes, and whether to count them as significant figures. Leading zeroes do not count, but trailing zeroes do count as significant figures. If you forget, just convert a value to scientific notation and count the significant digits. Related End-of-Chapter Exercises: 1, 2, 3, 11, 17.

Round the result to have the same number of significant figures as the measured value with the least number of significant figures. • Below are two examples. A) Write the product of 2.10 × 0.5896 with the correct number of significant figures. Step 1) 2.10 × 0.5896 = 1.23816 Step 2) 1.23816 = 1.24 (three sig. figs because 2.10 has three)
