People do different things while reading. Some like eating, some just like to drink coffee or tea and some do other things, but what I did when I was in school is different than this. I liked to listen music while doing my maths questions. When I asked this question in one of the community I joined, I got different kind of answers for this simple question.

1st the reason why I used to do this. I used to do this because I felt my concentration intact while music was on and going slowly in my ears with low sound. I felt a free mind and problems of maths solving easily. 

But I found that it is not for all. There are people who are unable to concentrate when music is on. Some people hate it and find it as disturbing.

So, what you guys think about is and what do you do while reading or studying?
