Question

good morning mates if any no is divided with itself it is equal to 1 but why if 0 is divided with 0 it is not equal to 1?​

Answer 1

Because see,

suppose,

it's your birthday today and you distribute one chocolate with one kid,

how many chocolates will one kid get?... 1

Now you distribute zero chocolate with 0 kids, how many chocolates will one kid get?...

It will not be 0 because there is no kid... so what will the answer be?...

The answer will be nothing but WRONG QUESTION!

And the mathematical term for Wrong Question is Undefined.

0 will be the answer when you distribute 0 chocolates with one or more kids, because then one kid will get no chocolate...
