Remember PEMDAS. So start with the parentheses and do the multiplication inside the parentheses first.
  1/2 (4+6*3) -9      multiply 6 and 3
  1/2 (4 + 18) -9     add 4 and 18                                                                   1/2 (22) -9           multiply 1/2 and 22
  11 - 9                   subtract 11 and 9
