What is zero over zero?

Question

I was puzzling over this question that a friend suggested to me. I have come up with no definite answer. What I thought was that:

$x/x$ is $1$ and
$x/0$ is UNDEFINED (or some people say it's $\infty$)

To explain this you need some weird quantum mathematics. When I scoured the internet for answers, all I could find was exactly what I found myself. Does anyone have a definitive answer (even if it's just definitely impossible).

Thankyou, yes. I didn't know the right place to look – William Pennanti Feb 26 '20 at 15:26 — William Pennanti, Feb 26 '20 at 15:26

According to Wheel Theory, $0/0$ is designated the symbol $\bot$.

While true, I think this probably will confuse OP more than help. Wheel Theory does away with a lot of the nice properties that the reals have. – Rushabh Mehta Feb 26 '20 at 15:46
