Eli5 why is a number divided by zero undefined?

Question

Example I have a pizza I cut it into zero pieces shouldnt it be still one whole pizza?
Since I didn’t cut it so it’s still whole

In: 0

Answer 1

Think about it.

10/5.

It means, basically, “take ten identical pieces, divide equally into five piles”.

So. 10/0 then. “Take ten identical pieces, divide equally into ZERO piles.”

That…that is impossible, if you boil it down. There can be no answer to that, because you cannot do it. You cannot expect an answer on something you are unable to do.
