Range[1, 9, 2]* Range[3, 11, 2] comes out to be {3, 15, 35, 63, 99} why is it 3,15,35,63,99?
...and if you were trying to compute the dot product, look up Dot in the Documentation Center.
May I suggest a divide and conquer approach?
What does Range[1, 9, 2] do? What does Range[3, 11, 2] do? What does "*" (Times) do when given lists?
Why should it be anything else?
In slightly more detail:
(1) What result are you expecting that is different?
(2) What have you checked in documentation that you are not understanding?
