What Arturo is saying is that if a and b are complex numbers,
then the conjugate of ab is the conjugate of a multiplied by
the conjugate of b.
 
Example:  a = 2+3i, conjugate = 2-3i
               b = 4- 2i, conjugate = 4+2i
 
Find conjugate of ab:
(2-3i)(4+2i)
= 8 + 4i - 12i -6i2
= 8 - 8i +6
= 14 - 8i
