Division by zero

Division by zero

Are you shocked!
Oh no! I am not taking about how to divide a number by zero. Actually, that is not possible. But, some of us asks why?
Why we can not divide a number by zero?
 So, let's discuss about the matter with a deep inner sight!
  Before we start our journey, let's highlight the matter with an real life experience.
   In family we always share many things between our family members. Let , in a family there are 7 members and there are 14 cakes , so each family member can get 14/7=2 cakes.  
Again think that, in a family there are 7 members but there are no cake or 0 cake.
Then each member get 0 cake. So, 0/7=0.
  But, can you think about a matter that, in a family there are no members (just suppose) and there are 7 cakes and you have to distribute the cakes among them!
  How is it possible!!!
  Yes, this is the fact in the case of 7/0 also.
     

Division by zero
Yes, this the hidden truth!

There is an another method to realise that, why division by zero is undefined.
We know that, If we divide a number (dividend) by another number (divisor), we have a result(quotient), (assuming that remainder is 0).
Now, if we multiply the quotient with the divisor we will get the dividend back.convere is also true.
As for example, 14/7=2 and 7×2=14 and conversely also.
That's right!
Now,  if we divide 7 by zero, i.e., 7/0 and let result is 7/0.
But if we multiply 7/0 with 0 what we get?
We get, (7/0)×0=7×(0/0)=7.(Assuming that we can divide 0 by 0)
But, we know that, 0 ×(any number)=0.
So, (7/0)×0= 0.
Thus, we get, two different results, i.e., a contradiction arises.
So, our assumtions are wrong.
So, 7/0 is undefined.

Here, we must remember that, 0/0 is also undefined, it is called the indeterminate form.
So, our, conclusion is division by zero is undefined.
