(B) For multiplication and division: The answer should not have more significant figures than the number with the least amount of significant figures. Example: 502 x 3.6 = 1800 Not 1807.2 * These last 2 rules can be called the Many-Places rule. For mult/div, how many significant figures is important. For plus/minus, number of places is important.
