1 INTEGERS – Product & Quotient

2 Multiplying Integers - remember our changing sign table ? + + changes to + - - changes to + + - changes to - - + changes to -

3 INTEGERS – Product & Quotient Multiplying Integers - remember our changing sign table ? - when multiplying integers of different signs, the results are exactly like the table above. + + changes to + - - changes to + + - changes to - - + changes to - (+) times (+) = + (-) times (-) = + (+) times (-) = - (-) times (+) = -

4 INTEGERS – Product & Quotient Multiplying Integers (+) times (+) = + (-) times (-) = + (+) times (-) = - (-) times (+) = - EXAMPLES :( +2 ) x ( +4 ) = 8

5 INTEGERS – Product & Quotient Multiplying Integers (+) times (+) = + (-) times (-) = + (+) times (-) = - (-) times (+) = - EXAMPLES :( +2 ) x ( +4 ) = 8 (- 2 ) x (- 4) = 8

6 INTEGERS – Product & Quotient Multiplying Integers (+) times (+) = + (-) times (-) = + (+) times (-) = - (-) times (+) = - EXAMPLES :( +2 ) x ( +4 ) = 8 (- 2 ) x (- 4) = 8 ( +2 ) x ( - 4 ) = - 8

7 INTEGERS – Product & Quotient Multiplying Integers (+) times (+) = + (-) times (-) = + (+) times (-) = - (-) times (+) = - EXAMPLES :( +2 ) x ( +4 ) = 8 (- 2 ) x (- 4) = 8 ( +2 ) x ( - 4 ) = - 8 ( - 2 ) x ( +4 ) = - 8

8 INTEGERS – Product & Quotient Dividing Integers - the same table holds true (+) divided by (+) = + (-) divided by (-) = + (+) divided by (-) = - (-) divided by (+) = -

9 INTEGERS – Product & Quotient Dividing Integers - the same table holds true (+) divided by (+) = + (-) divided by (-) = + (+) divided by (-) = - (-) divided by (+) = - EXAMPLES :( +8 ) ÷ ( +4 ) = 2

10 INTEGERS – Product & Quotient Dividing Integers - the same table holds true (+) divided by (+) = + (-) divided by (-) = + (+) divided by (-) = - (-) divided by (+) = - EXAMPLES :( +8 ) ÷ ( +4 ) = 2 ( - 8 ) ÷ ( - 2 ) = 4

11 INTEGERS – Product & Quotient Dividing Integers - the same table holds true (+) divided by (+) = + (-) divided by (-) = + (+) divided by (-) = - (-) divided by (+) = - EXAMPLES :( +8 ) ÷ ( +4 ) = 2 ( - 8 ) ÷ ( - 2 ) = 4 ( + 8 ) ÷ ( - 2 )= - 4

12 INTEGERS – Product & Quotient Dividing Integers - the same table holds true (+) divided by (+) = + (-) divided by (-) = + (+) divided by (-) = - (-) divided by (+) = - EXAMPLES :( +8 ) ÷ ( +4 ) = 2 ( - 8 ) ÷ ( - 2 ) = 4 ( + 8 ) ÷ ( - 2 )= - 4 ( - 8 ) ÷ ( + 2 ) = - 4
