well my boi the first one that looks like a 0 with a line through it is theta which is a letter of the greek alphabet not a number. and infinity can't really be defined so i wouldn't call it a number but if i had to choose i would go with infinity

[math] \displaystyle
\boxed{0 < p < 1} \\
p^n-1 = (p-1)(p^{n-1}+p^{n-2}+ \dots +p+1) \\
\dfrac{p^n-1}{p-1} = \sum \limits_{j=0}^{n-1}p^j \\
\displaystyle
\lim_{n \to \infty} \dfrac{p^n-1}{p-1} = \lim_{n \to \infty} \sum \limits_{j=0}^{n-1}p^j \\
\displaystyle
\dfrac{0-1}{p-1} = \sum \limits_{j=0}^{\infty}p^j \implies \dfrac{1}{1-p} = \sum \limits_{j=0}^{\infty}p^j

To waste your lives feeling so certain of a thing, only to see it dismantled from the inside out...
Now, suddenly, the rug has been pulled from under the feet of you dreamers. I can imagine how lonely you must feel deep down inside, bearing such pain.
That is the beauty, that is the terror of mathematics. There's no getting around a proof.
Don't blame yourselves; instead, blame history, and the human spirit. To whet mankind's thirst for knowledge, history gave us Galileo, Newton, Darwin, Einstein, Godel, and now Wildberger gets his turn.
You must either move on, or get left behind. The choice is yours.

Sure, but this isn't about constructing a response and inventing a category for the term "number," it's about reversibility of operators in a group or field. Since 5,761,312 * 0 = 0 as well as any real number, the total set of valid solutions to the division is [math]\mathbb R[/math]. Zero was never invalid as an answer, but that was never the issue. 0 * 0 = 0 is more like a special case of n in the rule n * 0 = 0.
