去旅行之前一次過出10題問題，睇下我去完旅行返來，大家係咪已經好聰明咁解答哂先 :D
D問題咩種類都有D，由數學至醫學至物理 ^_^
睇下你地邊個答到最多 ;)

其中幾題包括：
4. If x and y are positive integers, find all the solutions for (x + y) ^2 = 10x + y.

5. Find 1 + 2 * (1/3) + 3 * (1/3) ^2 + 4 * (1/3) ^3 + 5 * (1/3) ^4 + ….

6. Find the remainder when 11111111111111…111 (1000 digits in total) is divided by 12.
