actually i am a student and i would like to know the ways of doing maths easily and how to sit while doing maths.and how should our mind state be and also while doing what will be the best place to do maths like balcony or some other place like that.

Mathematics is a subject which requires a lot of question practice. So the best way is to solve as many problems as possible.

Next thing is that maths must be chosen when we get boared with a topic in any other subject 

and nextly the place to study must be chosen where we feel most comfortable

comfortable in which way???
