When I first contacted with numbers, I was deeply attracted by this subject. Without any shadow of doubt, I would choose mathematics as a degree. I always feel excited when I am trying to solve challenging mathematics problems.That time when I was a member of "Mathematical Olympiad" class in my primary and secondary school is the most wonderful memory in my life. Talking about mathematical questions with other members all the day, playing mathematics games, practising solving maths problems. As a little boy I would rather spend all the time discussing mathematical topic with my father than play games.
