Using Windows XP calculator if I click 6 / 2 * ( 1 + 2 ) =3D, I get 9.
If I enter exactly how the OP wrote (without the * ), then I get 2.

It seems a bug in the parser, that ignores an error (lack of an
operator) and gives a nonsensical result.

BUT if I press =3D again, I get 0.666666...67, which means that the
calculator thinks its last executed operation was a divide by 3.
