Many thanks to my excellent performances in Mathematics Olympic, I went to high school and middle school without taking the entrance exams.
Back then, I really obsessed with mathematics. Thinking through a mathematical problem and coming up with a solution were a great pleasure for me. Each time, after thinking and letting my mind wander, and finally reaching the result or proving the theory, a feeling of relief and accomplishment settled down on me.
Mathematics is the gymnastics of brains. Only with pen and paper, you can exercise your brains by cracking mathematics problems.
I hope more and more kids can enjoy the pleasure of mathematics.
