**The rule for addition and subtraction is different; you won’t have to memorize that one. However you will need to know the rules on scientific notation and sig figs. The number of sig figs comes from the number written _____ the times sign. 3.50 x 1023 = ___ sig figs; 5.0 x 10 -4 = ___ sig figs; 3 x 10-4 = ____ sig figs

3. In multiplication and division, carry the result to the same number of significant figures that there are in that term which has the least number of significant figures. For example: 3.95 x 5.1 = 20.145, rounded to 2 significant figures = 20. 34.2/6.29934 = 5.429140196... becomes upon rounding 5.43. 4.

The potential ambiguity in the last rule can be avoided by the use of standard exponential, or "scientific," notation. For example, depending on whether the number of significant figures is 3, or 4, we would write 50,600 calories as: 5.06 × 104 calories (3 significant figures)5.060 × 104 calories (4 significant figures) What is a "exact number"?

This is the most common rule for sig figs we will be using. Use this for all multiplication or multifunction equations. Use the . lowest number of total sig figs. in your equation for your answer. Example: 6.5 m x 687.3 m = 4467.645 m, but because of sig figs, your answer will be 4.5x103 m (2) (4) (7) (2) Addition / Subtraction:

The following rule applies for multiplication and division: The LEAST number of significant figures in any number of the problem determines the number of significant figures in the answer. This means you MUST know how to recognize significant figures in order to use this rule. Example #1: 2.5 x 3.42.
