Heh, I actually have a theory on the cause of all this commotion: Us being acquainted to more complex mathematics, mainly algebra, we tend to forget the simplicity of simple problems such as this. We are very used with the x and y equations that we try to apply it to this one too (not that it shouldn't; I'm talking very down to earth here).
For example, take the equation x˛/y(x+1). Upon seing the equation, we would do the groupings first and then distribute it, as we know we can barely do anything with dissimilar variables. Since almost every problem bombarded to us usually involves dissimilar variables, it becomes instict to simplify everything first and mostly do division last.
My teacher always told me: "Once you become an expert engineer knowing complex things, you would tend to forget even the simplest of equations"
