剛剛看到youtube有人證明 0 = 1
而且過程完全沒錯
以下是過程
-20 = -20
16 - 36 = 25 - 45
4^2 - 4*9 = 5^2 - 5*9
4^2 - 4*9 + (81/4) = 5^2 - 5*9 + (81/4)
4^2 - 2*4*(9/2) + (9/2)^2 = 5^2 - 2*5*(9/2) + (9/2)^2
(4 - 9/2)(4 - 9/2) = (5 - 9/2)(5 - 9/2)
(4 - 9/2)^2 = (5 - 9/2)^2
4 - 9/2 = 5 - 9/2
4 = 5
4 - 4 = 5 - 4
0 = 1
挖操
我剛看完整個目瞪口呆
原來 0 = 1
有人能推翻它嗎？
有卦？
