0

The most mysterious and complex number. Basically zero is nothing and something at the same time. Then less than zero is written -1 this totally contradicts the whole number.

The number 0 exists and then yet it represents that something doesn't exist!

0⁰

Still a mystery, is it 0 or 1?, Or even ∞?
Literally the same as 0×0

Person: what's 0⁰?
Person 2: "Error! Brain.exe has stopped working!"
