  1. RULE OF NEGATIVES Made by Yue Jun (2011)

  2. NEGATIVE & POSITIVE & MULTIPLICATION a x b = (+)(+)ab = +ab -a x b = (-)(+)ab = -ab a x –b = (+)(-)ab = -ab -a x –b = (-)(-)ab = +ab

  3. NEGATIVE & POSITIVE & DIVISION a / b = (+)a/(+)b = +a/b -a / b = (-)a/(+)b = -a/b a / –b = (+)a/(-)b = -a/b -a / –b = (-)a/(-)b = +a/b

  4. GENERAL RULE If there is an odd number of negative numbers, the sign is (-) If there is an even number of negative numbers, the sign is (+)

  5. EXAMPLES (-a)3 = (-a)(-a)(-a) = -a (-b)3(-a) = (-b)(-b)(-b)(-a) = +ab3 Therefore, what is (-c)220? Answer: (-c)220 = c220
