做 個 有 趣 的 人

假設

No Study = Fail

Study = No Fail

____________________

No Study + Study = Fail + No Fail

(No + 1)x Study = (No + 1)x Fail

So.... Study = Fail 得証


--------------

反證

No Study + Study = Fail + No Fail →移Fail到左式

No Study - Fail + Study = No Fail　→(No Study - Fail = 0)

故 　Study = No Fail

--------------
No Study + Study = Fail + No Fail
No Study + Study = No (Study + Fail) →( Fail = No Study )
Study = No (Study + Fail - Study)
∴Study = No Fail
