That's not playing devil's advocate. That's you not understanding how the calculator was programmed.
A graphing calculator in which you can put (9+3x2) before pressing enter is different than a adding calculator in which you can only do sequential binary operations (9+3, enter, x2, enter).
The calculator is programmed exactly to do as it was. Both calculators are correct in their programming. It's you who mistyped what you intended.
