And you were correct, but during my time here I have noticed downvoting here is not about correct/incorrect answers. Sometimes changing something doesn't attract the downvoters.

comment Differentiating $y=x^{2}$
If the original term was $2$ of $x\mathrm{d}x$, wouldn't it have to be written out as $2x * 2\mathrm{d}x$ Why? If instead of $x\mathrm{d}x$ it was $x c$ should it end up as $2x * 2cx$ instead of $2cx$?
