Actually, it is possible to divide by zero, it's just that teachers only say "You mustn't divide by zero!" and other codswallop. If you divide by zero, there are two possibilities:
First, if we say 6 divided by zero is x, x times 0 will have to be 6. But there is no answer to this, so there is no answer.
Second, let's say x is any number. 6 divided by 1 is 6. 6 divided by 0.5 is 12. 6 divided by 0.1 is 60. The result keeps getting bigger if x is getting closer to zero. So 6 divided by zero will actually be infinity.
Now, if we actually could divide by zero, there will be a fallacy.
With the assumptions '0 times 1 is 0' and '0 times 2 is 0', divide both sides by zero. This will simplify to '1=2' 1=2?? That surely doesn't make sense! (This also can mean 1=9999999999999999999999999999999999999999999999999999999999999999)
Also, let '1=x'. If we multiply both sides by x, we will get 'x=x squared'. Then, if we subtract both sides by 1, we will get 'x-1=x squared-1'. Now, if we divide both sides by x-1, we will get '1=x+1'. x was 1, so 1=2!
Tell me what you think!
Wow! I think I understand why the teachers told me to not divide by zero, there are so many complications! Also, I never imagined that the result of something divided by zero could be infinity! Thank's Siyoung!
