Although maths is quite an interesting subject but to be honest, I am a bit scared of maths. In my twenties, we had some advanced math lessons in college that I dreaded. But, since I was a student of the science department, apart from maths, my physics and chemistry were also very difficult. So to overcome my weakness in maths, I used to take tuitions from our college's maths professor as well as do the classes of our country's best Dhaka University big brothers online at home. After a lot of hard work in this way, my maths weakness was removed. Thank you very much for presenting Maths Variables and Expressions in such a beautiful, simple and easy way.
