Question

what is the answer of 0÷0

Answer 1

Zero 0. The answer will be zero because if we divide zero by zero the result will be zero

Answer 2

Answer: Not defined.

Explanation: Division of zero by zero has benn discussed long in history. Possible choices are

1. Zero : As division of any fraction with zero as numerator is zero.

2. One: Any number divided to itself gives one.

3. Infinity: Any division with denominator zero gives infinty.

Truth is that all this common sense fails with 0/0. 0/0 carries no meaning in itself and is mathematically incorrect to write that expression in any place. No accurate calculations and answer of real life problems gives answer 0/0 and if you get that as an answer, for sure, you've done a wrong calculation. So, that's mathematically not defined or it leaves you with no choices to choose any number.

Some people say that answer is not defined or infinity. They confuse 'not defined' with infinty. But infinty leaves another problem that any choice of number can be correct. So 0/0 = 0,1,2 or any number, which is incorrect.

So answer is solely Not defined.
