This question Why is Mathematics Complicated! has been closed, but I consider it a very important question and also I don't see why it is not appropriate for this site?
Can you please explain why it is not acceptable or even better help to reopen it?
It is true that the answer to the question is not a number - so one cannot simply take the question and feed it into the calculator (or look it up in the dictionary like some of the other recent questions) and post the result as an answer, but it is my hope that this site doesn't become a human powered calculator. The singular thing which a site like this is can do, that others cannot is have people who have understood things share their understanding - this (deep) question should be a good catalyst for this but instead, to my disappointment is just shut down!
