I disliked mathematics for most of my life. Then someday I decided to give it a try and I think it is beautiful now. At the moment I'm studying mathematics at an undergraduate course.

Don't mind the lack of pattern in my questions, I'm having to learn some new concepts and also some things I should have learned when I was younger.
