RE: Casio anomaly or gremlin or bug...
This may fall under the same category of squaring negative numbers on algebraic calculators: where on some:

-3^2 returns -9. The calculator treats squaring as priority over negation - prevalent in TI graphing calculators.


For the record:

TI-84 Plus CE:
6/2(1+2) returns 9

HP Prime:
6/2(1+2) returns 9

The HP48GX doesn't allow implied multiplication. I tend to agree with this; in practice I inserting multiplication signs.

I think in this case, I would side with caution and put an additional set of parenthesis if you meant 6/(2(1+2)) or a multiplication sign if you meant 6/2*(1+2).

Which brings up a question, should implied multiplication on calculators be allowed at all?
