.
When the person posts 3 posts with 3 problems in each, it is just "industrialism".

In this site we do not serve industrialists.


We help student to solve their problems.

We teach them, we explain something to them . . .


But it is not our goal to work INSTEAD of students.

Or for industrialists.


---------
The rule of this site is:

        One and only one problem per post.
