This is a rather philosophical question, but reflects the fact that essentially the same question can be asked at different levels of mathematical sophistication and with differing motivation.
Here are three, the last of which has been closed:
Trigonometric equation - solution required
Solving a problem about overlapping circles - help in estimating solution required
Identifying centre of mass of a semicircle - elementary insight required
I'm guessing the answers to the first would not help the person who asked the second very much. So can essentially the same question be different because of the apparent mathematical sophistication of the person who asks it?
