Question

Why is 0/0 undefined?

Answer 1

Because you cannot say what the (unique) result is!

Explanation:

Try to think at a possible solution of `0/0`:
Could we choose `3`?
Yes because:
`0/0=3`
So rearranging: `0=0×3=0` it works!
But....also `4` works...also`123235467` works....ANY NUMBER works!
So if I ask you for the result of `0/0` you'll answer: "all numbers"!!!
Hope it helps!
