Okay, I got you...
2) 2
3) 6
4) 33
5) 5
6) 19
No. (12+6)/2=9
and 12+6/2=15
This happens because in order of operations parentheses come first, so you would do that and get 18. Then you would divide 18 by 2 and get 9.
On the second one you would do division first (6/2) and get three, the you would add 12 and end up with 15.
Hope this helps :)
