"Suatu hari, ketika saya berhasil dengan baik di kelas dan telah menyelesaikan pelajaran saya, saya duduk di sana mencoba untuk menganalisis permainan tic-tac-toe ...

--- Martin Gardner

Versi Bahasa Inggris

One day, when I was doing well in class and had finished my lessons, I was sitting there trying to analyze the game of tic-tac-toe... The teacher came along and snatched my papers on which I had been doodling... She did not realize that analyzing tic-tac-toe can lead into dozens of non-trivial mathematical questions.
