다음 억지논리를 반박하세요.
0=1이에요
왜냐하면
여기 0.999999...과 1.000000000...1이 있어요.
일단 0.99999999...는 1이고, 1.0000000000000...1도 1이에요
왜냐하면 0이 무한이 있으니까 1은 소용이 없는 거에요
그럼, 이건 1=1로 만들 수 있지만, 오른쪽은 원래대로 1=1.000...1로 할게요
그러면 여기에 2를 곱해요
계속 곱해요
무한히 곱해요
그러면 둘 다 무한=무한이 되죠
하지만 무한이 곱했으니 1.00000000...1은 2.00000...2... 이렇게 해서 결국 이 소수점 아래 값은 1이 되요.
그럼 또 무한히 빼요.
그럼 아까 소수점 아래는 1이 됬으니까
다 뺀 다음에는 1=2가 되요.
여기서 하나를 더 빼요
그럼 0=1이 되요
고로
0=1이에요
