I believe the answer is 1. Since there's no symbol in between the parenthesis and the 2, we treat it as a multiplication of all the numbers in that parenthesis (in this case, the 1 and the 2). Then, it's just a simple priority operation: 6/(2+4)=6/6=1. Please correct me if I'm wrong.
6/2 = 3
1+2 = 3
3*3= 9
the answer is nine
