Nội qui tham gia "Giúp tôi giải toán"
1. Không đưa câu hỏi linh tinh lên diễn đàn, chỉ đưa các bài mà mình không giải được hoặc các câu hỏi hay lên diễn đàn;
2. Không trả lời linh tinh, không phù hợp với nội dung câu hỏi trên diễn đàn.
3. Không "Đúng" vào các câu trả lời linh tinh nhằm gian lận điểm hỏi đáp.
Các bạn vi phạm 3 điều trên sẽ bị giáo viên của Online Math trừ hết điểm hỏi đáp, có thể bị khóa tài khoản hoặc bị cấm vĩnh viễn không đăng nhập vào trang web.
Câu 1 : Nhà thông thái đó đã suy luận như sau :
- Ai cũng cười vì tưởng trán mình không nhọ , hai người kia thì cười nhau còn mình thì cười họ.
- Thế nhưng , nếu trán tôi không nhọ thì hai người kia đều sẽ phát hiện được ngay trán mình bị nhọ. Chẳng hạn người thứ ba , khi thấy người thứ hai cười anh ta biết ngay là cười anh ta chứ không phải cười tôi ( vì tôi không bị nhọ ).
- Trong thực tế hai người kia đều cười và không phát hiện ra trán mình bị nhọ. Vậy trán tôi cũng bị nhọ.
Câu 2 : Cô đầu bạn hỏi là cô : Nhị
Cô nói xen vào là cô : Nhất
Hôm đó là thứ : Ba
