Sect 1.7 Properties of Quotients

 

Division is a convenient way of denoting multiplication by the multiplicative inverse of a number.

 

                        Definition:  

 

Ex.  = (-45)(  )

               = (-9 5)  

               = - 9(5   )

               = - 9(1)

               = -9

 

*Remember that division by zero is not defined.

 

Order of Operations:

1. Simplify powers
2. Simplify products and quotients from left to right
3. Simplify sums and differences in order from left to right

 

 

Ex.   [ - 8 + 3(8 ÷ 4)

          [ -8 + 3(2)]

           [ -8 + 6]

            [ -2]

 

            -1
