I probably do not understand the forum https://mathoverflow.net/questions

Have noticed that if someone asks how to solve any equation - then this post with a question quickly removed. Okay. Suppose this question is easy, but often no one knows how to solve any equation.

Often do not understand and do not know the method of calculation and the post is still removed.

Or alternatively write a triviality, but it is perceived well. When the task of generalizing and trying in General to solve post again removed.

I understand that modern mathematics doesn't like the formula, but not to the same degree. If we write the solution of the equation, then it will be removed for sure.

Can explain to me why such hostility?
