is x÷1/2y=2xy or 2x/y?

OpenStudy (anonymous):

as it is written.. it is 2xy... because of order of operations.. only divide and multiply so do them left to right... \[\huge x\div1/2\cdot y \]

OpenStudy (anonymous):

thanks

OpenStudy (anonymous):

wait... that's wrong...

OpenStudy (anonymous):

why

OpenStudy (anonymous):

the answer by order of operations is \[\huge \frac{xy}{2} \]

OpenStudy (anonymous):

how come?
