Nope, PEMDAS is the correct order of operations
Parenthesis
Exponents
Multiplication and Division
Addition and Subtraction
So the 3/(1/3) should be done first and equals 9. Then you're left with 9-9+1 = 1
EDIT: just realized you were trying to answer the second question...you're right
6/2(1+2) = 3(3) = 9
