Order of operations - what is 6÷2(1+2) ?

[Steve Simpkin]

Some other examples of different calculator interpretations of the rules of operator precedence.

My HP-48GX returns an answer of 9 when I enter '6/2*(1+2)' EVAL or 1 if I use the Equation Writer and use implied multiplication of 6/2(1+2) which is converted to 6/(2*(1+2))'.

My Casio fx-115ES Plus returns an answer of 1 if I enter 6/2(1+2) or 9 if I enter 6/2*(1+2).

WolframAlpha returns 9 to 6/2*(1+2) or 6/2(1+2).

Google returns 9 to 6/2*(1+2) or 6/2(1+2).

My Prime app returns 1 if I enter 6/2*(1+2) or 6/2(1+2). I can't seem to use an implied multiply on the Prime without it being converted to a *.
