The rules apply separately to multiplication and division, addition and subtraction, and to logarithms. àSignificant figures involving multiplication and division When multiplying or dividing two approximately known numbers, the number of significant figures in the result is the smaller of the number of significant figures in the factors. Here are some examples. 1.23μ0.9... • all other zeros are not significant. Using these rules 65.00 has four significant figures but each of the numbers 65, 6500, and 0.0065 has only two significant figures. Example When performing calculations the final answer should contain only as

Title: Slide 1 Author: Heinrich, David Created Date: 11/25/2013 12:35:30 PM dead man walking helen prejean pdf In this section I lead students in determining the significant figure rules through giving them examples and having them notice the patterns (it is the first part of the PowerPoint). I have found that by leading students into determining the rules they are much better at remembering the rules throughout the year.
