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

So dividing by zero Being NaN for your example is not that you are cutting a pizza zero times(which is why any 0/1 = 0 meaning you cut it 0 times) you have zero pizzas and you need to cut it at least 1 time. You can’t cause you got no pizza to cut
