  1. The number I pick was 1, I +5 to it which = 6, then 6 x 2 = 12 then 12-4 = 8 and when I divided it by 2, I don't get 3?

  2. Hey, the result cant always be 3 as I did it with 6 and got 9, you would have to the square root that number to get 3. I don't agree with your answer as I cant see why you wld just multiply the degrees. Anyway thank you for your help and sorry I couldn't be more help with your problem.
