  1. Sections 3.6 – 3.7 Multiplying and Dividing Integers

  2. Multiplying or Dividing Integers • SAME SIGN  POSITIVE • DIFFERENT SIGNS  NEGATIVE • ( + ) • ( + ) = + • ( - ) • ( - ) = + • ( + ) • ( - ) = - • ( - ) • ( + ) = -

  3. Definitions • Inverse operations: • What undoes addition? • What undoes multiplication? An operation that undoes the original operation. subtraction Division.

  4. Multiplication and Division with 0. = 0 Which one of these is not correct? = 0 = 0 undefined = 0

  5. Find each Product • - 8 (7) = • -4 ( -6) = • (3) • (0)= • 6 • - 3 = -56 24 0 -18

  6. Find each Product • - 80 ÷ 5 = • -45 ÷ -9 = • -8 ÷ 0 = • 36 ÷ 3 = -16 5 undefined 12

  7. Homework : pages 166 – 167 4 – 24 evens! Pages 172 – 173 4 – 24 evens!
