Casio anomaly or gremlin or bug...

But apparently it's more common for calculators to omit that rule, and to give all multiplications the same precedence, no matter how they are written. If you search for "implied multiplication" on this page, you'll see a good explanation of both interpretations.

Bottom line: this notation is ambiguous. Therefore it should simply be avoided, which is why HP's RPL and Prime's CAS don't allow it.

So, you're saying the TI and HP results are correct? What rules are present when +/- or x/: are on the same level in an expression?
