    Sorry but both my phone calculator and TI-84 calculate 1/2X

    …and they’re both wrong, because they are disobeying the order of operations rules. Almost all e-calculators are wrong, whereas almost all physical calculators do it correctly (the notable exception being Texas Instruments).

    You are saying that an implied operation has higher priority than one which I am defining as part of the equation with an operator? Bogus. I don’t buy it. Seriously when was this decided?

    The rules of Terms and The Distributive Law, somewhere between 100-400 years ago, as per Maths textbooks of any age. Operators separate terms.

    I am no mathematics expert… never heard this “rule” before.

    I’m a High School Maths teacher/tutor, and have taught it many times.
