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

Let’s try to calculate your example:

1) 1 divided by zero, how many times does zero go into 1? (no matter how many times you have nothing, will it never be equal to one)

2) Now after you have done the above, how much is left? (1 is left)

Repeat the above for all eternaty, and you’ll still have one left. 🙂
