Let x be any real no.

Then, if we do as follows:

\(\frac { 0 }{ x } \) , we get 0 as only \(x\times 0\) is 0

If we do \(\frac { x }{ 0 } \) it is indeterminate or not defined.(I know the reason)

But if we do \(\frac { 0 }{ 0 } \) we say the answer is 0. Is it really 0 or indeterminate because 0* any no. is 0 so should'nt the answer be not defined.

Please help.

TopNewestAny number divided by \(0\) is undefined.

Dividing by a certain number is the same as multiplying by its multiplicative inverse.

The multiplicative inverse of \(0\) is not defined. You can try to define it, but you're going to run into inconsistencies. You can try to patch those inconsistencies by giving \(0^{-1}\) more properties. Then you're going to run into other inconsistencies. Finally you may be able to do it, but it won't be of much use.

Sorry Kushagra but your answer is more lame than my doubtLog in to reply

Hmm the answer should be not defined because 0/0 can also be equal to 1 like 2/2,3/3 are equal to 1 and it can also be 0 because 0 has no value ,so the answer can't be defined ^_^ – Divij Bahl · 11 months, 3 weeks ago
