Last time I saw this kind of challenge it was on reddit and I just replied with ℝ, but people brought up that this leaves out complex numbers. I’ll now contend, however, that any number not included in that isn’t real.
You could use ℂ
Quaternions hello?
What about quaternions and octonions and …
x
I prefer $
Just like birds, complex numbers aren’t real!
Screw you sqrt(-1), you aren’t even a real number, you poser!
Nope, you fell for the classic sibling blunder:
What about INFINITY PLUS ONE!?
It’s Infinity! Infinity -1? also infinity! Well what about infinity times infinity? Believe it or not, infinity! ♾️
What about infinity times zero?
For that one we’re going to call my good friend L’Hôpital. That guy rules!
Infinity gangsta when aleph null walks in
Everyone is mentioning the imaginary (and, presumably complex) number domains, but not quaterions and other higher dimensional number sets.
I’m going with defining a describeable number as any number that, given any finite period of time and any finite amount of resources, could be uniquely described to another entity with the ability to read and understand the language it is being described in, then saying all numbers are either describeable numbers (Despite the fact that these are almost laughably uncommon in the scheme of all numbers, I have diligently prepared an example: “2”), or indescribeable numbers (so much more common, and yet I can’t give even a single example).
Eldritch numbers.
I cast set theory?
Where is i? Is it safe? Is it alright?

Aren’t there numbers past (plus/minus) infinity? Last I hear there’s some omega stuff (for denoting numbers “past infinity”) and it’s not even the usual alpha-beta-omega flavour.
Come to think of it, is there even a notation for “the last possible number” in math? aka something that you just can’t tack “+1” at the end of to make a new number?
Which of the infinities? There are many, many :D
The smallest infinity is the size of the natural numbers. That infinty, Aleph zero, is smaller than the infinity of the real numbers, Aleph one. “etc.”
No matter what Wikipedia says, Aleph Null is the real way to say it, because it sounds so much cooler
I agree. But I’m Danish, where zero is called nul and and Ø is in the alphabet, so I try to cool ot a bit with the coolness.

Oh no! Please don’t tell me there are infinity infinities!
Unfortunately yes there are and it’s a very big infinity of infinties…
Hi! I’m a mathematician, and if you want to know more about infinity, I recommend this video: https://youtu.be/23I5GS4JiDg
After reading how this thread is going I’m half expecting this to be a Kurzgesagt video or something equally “cutesy existential dread” inducing lol. Let’s see what do I find!
I thought it was ‘R’, for the set of all real numbers.
Oh, so complex numbers are not numbers now?!
Depends on the bit limit
U
Ω
UΩU
UωU
Didn’t it 0,1,2,3,4,5,6,7,8,9?
That’s just all the Arabic numerals
Doesn’t include “i”
i isn’t a real number, you imagined it
From gatekeeping to gaslighting in 2 comments. Not bad!
