1-5Multiplying and Dividing Integers : 

1-5Multiplying and Dividing Integers 1-5 Multiplying & Dividing Integers: Rule: Applies to BOTH multiplication & division. (+)(+) = + (+)(-) = - (-)(+) = - (-) (-) = + Multiplication and division of integers is cut & dry! No worrying about which absolute value is larger or whether you have to change any signs!!

1-5Multiplying and Dividing Integers : 

1-5Multiplying and Dividing Integers 1-5 Ex. 1. Simplify each expression. a) 5(-4) = b) -14(-4) = -20 56 7 c) -21  (-3) = d) (-15)  (5) = e) (-6)  (2)(-8) = -3 24

1-5Multiplying and Dividing Integers : 

1-5Multiplying and Dividing Integers Ex. 2. Evaluate y ÷(x – y) – yz + x for x = 6, y = -9, and z = –2. -9(6 – (-9)) – (-9)(-2) + 6 -9(6 + (+9)) - (-9)(-2) + 6 -9(15) - (-9)(-2) + 6 -135 – 18 + 6 -135 + -18 + 6 -153 + 6 -147
