Đề bài : Cho tổng 1 + 2 + 3 + 4 + ... + 49 + 50. Liệu có thể liên tục thay 2 số bất kì = hiệu tới khi được kết quả = 0 hay không :

                                       Bài làm :

Ta đặt A = 1 + 2 + 3 + 4 + 5 + ... + 49 + 50 

Dãy số tự nhiên liên tiếp từ 1 - 50 có 50 số, trong đó số các số lẻ = số các số chẵn

=> 50 : 2 = 25 ( số lẻ ) => A là 1 số lẻ

gọi a, b là 2 số bất kì của A, khi thay tổng a + b = hiệu a - b thì A giảm đi :

     ( a + b ) - ( a - b ) = 2 x b

Hiêu của 1 số lẻ và 1 số chẵn luôn luôn là số lẻ nên sau mỗi lần thay, tổng mới vẫn là 1 số lẻ 

Vậy không bao giờ có kết quả = 0

Among my favourite sports and hobbies, I like swimming the best for several reasons. Firstly, I think playing in the water could bring great joy.
