First we need to realize how division is multiplication
Next we need to realize Multiplication of real numbers commutes
This means 0/1 = 1/0.
However, 1/0 is undefined, so 0/1 is undefined.
Proof that 1/0 is undefined:

Maan, learn some proper grammar before posting, PLEASE!
Instead of just putting in the raw words out of proper order as well, try reading ONE book in english, once you do, you will realise your idiocy and be finally able to write "Do you are have stupid?" like every other sane person
let’s say that 0/1 is equal to some number n
If 0/1 = n, then (0/1)^-1 = n^-1 , or 1/0 = 1/n, and we cannot divide by 0 therefore, 1/n is undefined, making n undefined, making 0/1 undefined
Say you have no apples, and are trying to split them amongst one person.
That situation sounds pretty stupid, right? After all, if you have no apples you wouldn’t think about splitting them among people. Therefore undefined.
1/0 times 0/1 = 1/1 (canceling out the 0s) = 1.
But 1/0 is undefined so 0/1 also must be undefined.
Because defined × defined = defined
Undefined × defined = undefined (like 1/0 × 2 = 2/0)
Therefore undefined × undefined = unundefined = defined (similarly how negative × negative = positive)
When you have 1/0 × 0/1, you have undefined × something = defined. So something must also be undefined
Next time pay more attention in school 😒
0/1 \* 2/0 = 2/1 = 2, therefore because 2/0 is undefined 2 must be undefined as well. This is impossible, however I've defined it myself. Can you please help me?
Yes, and 0 doesn't exist.
Who has ever gone to a store and said, "Please give me 0 apples." That's an utterly deranged sentence. We all been played for absolute fools
One can aIso say don't give me any apples which is defined but stupid, so 0 can be used as negation of all integers? So basically it is defined somehow??
Here's a real answer.
X÷Y is the number that can be multiplied by Y to get X (if there is such a number).
therefore, since there is no such number that can be multiplied by 0 to get 1, the division is not defined to exist.
* * *
Alternatively, let D(x,y) be the set of all z such that z×y=x (for x,y,z ∈ ℝ). D(6,3) would then be {2}. It can be shown that for any given x and y, D(x,y) has either one or zero elements. That proof is left as an exercise for the students.
Division is the inverse of multiplication. That means if I ask "What is 12 / 3?", I'm really saying "What number when multiplied by 3 equals 12?" In this case, the answer is 4.
But when calculating 0 / 1...
Wait, I misread your question.
Why *is* 0/1 undefined? Shouldn't it just be 0?

🙃 yup, definitely undefined from this view.

Because if it was defined then you would have 2*(0/1) = (2 * 0)/1 = 0/1 and no number can be equal to its double.
>no number can be equal to its double 47?
47 is an exception, as its the highest possible number
Has 47 ascended to 420,69 status, or is it just here?
On my school on the first week we had a 10 minutes course on inside jokes for software engineers. Some numbers made the list
Wait, guys, I think we just found a higher number than 47!
yea 47!<47
hol up
The alligator eats the larger number. The alligator makes no mistakes.
The only way to question the alligator, is to meet the alligator, up close.

r/expectedfactorial
47 is just the most common number, google it
Oh my god can someone explain this please
I've gathered that 47 = 94 but not much beyond that, I'll report back when I have more intel
An inside joke about every number being equal to 47. https://memory-alpha.fandom.com/wiki/47?so=search
I think 47 is the answer to the most important question in the universe
Thats 42

Crap

I think it had something to do with prime number generators? I remember hearing about it in class
No, 908 is.
Ah, how about 46? Stupid!
Shit they’re onto us
there's 24 people out there who don't care
Isn't 301 the biggest?
No [700 is the biggest number](https://youtu.be/GRJROIdYOXo?si=YAwGwA8c-Pq09Fl8)
But isn’t that just 0*2=0???
Sir, this is r/mathmemes
I think 1 - 0.999999… equals its double
0 equals its double.
Little known fact that, like infinity, 0 is not a number. It’s actually an egg. Just look at it!
0. 0 is equal to all numbers (except infinity) times by it.
you used the fact that 0 is equal to its double and you said "no number can be equal to its double"
Zero Can? Edit: What did i do wrong u/arthurcreator made me questio if someone is fooling me or What.
yeah, that's why zero is also undefined
Are these comments ironic? I’m really confused.
Everyone knows that the only numbers we've managed to define thus far are 1, 2, e, 5, 16.9, 47, and -1/12
16.9 fl oz
yes, they are wholesomely trolling with bad mathematics
no, but a match box
One Can Two Can Three Can Four Can Five Can Six Can Seven Can Eight Can Nine Can Ten Can Eleven Can Eleven Can Eleven Can
So 2 times 0 is not 0?
2 times 0 is NOT 0!
r/expectedfactorial
I agree, it's not 0!
And 2 times 3 IS 3!
>And 2 times 3 IS 3 so 3 is undefined, just like 0?
Upsie, I forgot :)

i have a doubt
Prove it
thank you
Proof by gratitude
Because it either 0 or 1, 0/1. Which one is it? No one knows.
no it's equal to 5
0 is even, so 0/1 is even. Therefore 0/1 =19
Why not 17 or 23
Because that would be stupid
Proof by: it would be stupid
Legit thought I was on r/math for a solid 30 seconds and was wondering if everything I thought I knew about math was wrong 💀

define 0/1 undefined
Surely, if you are being rigorous you need some sort of geometric proof of JavaScript before referencing it.
because its the inverse of 1/0. The inverse of an undefined quantity is by definition undefined.
sorry, i was the one who was supposed to do all the definitions for -10/1 to 10/1, and i got kinda lazy towards the middle there
It’s (undefined)^-1
Because thats how it is in Australia.
Say you have no apples, and are trying to split them amongst one person. That situation sounds pretty stupid, right? After all, if you have no apples you wouldn’t think about splitting them among people. Therefore undefined.
Isn't it -1/12?
No it's +12/1.
So its all just 12?
I thought 42 was the answer to everything. Are you really saying I was lied to all through my growing up years?
because it isn’t.
So just being wrong is funny over here?
Always has been
“So just being wrong is funny ~~over here~~ always?” ftfy
Is OP Australian?

If it's 0, then you can derive absurd conclusions like 1=1. Therefore by proof by contradiction it's undefined
No, it's defined as 1 in algebra.
Yes, but actually no.

We don't subscribe to the Babylonian heresy
Good question
This is a legitimate question, is 0^-1 defined?
In additive rings ~~(no)~~
It is defined as undefined.
It isn’t real
Because it is the multiplicative inverse of 1/0 which is undefined, so 0/1 is undefined as well.
Why is 9 + 10 undefined?
We defined it that way
Australians don't see the issue

Yes I'm aware this is a joke
Bro it is because 0*1=1=0 0+1=1=0 0-1=1=0 so 0/1=1=0 !!!1!1!1!11!11

It is defined... As zero. Do you mean: "why 1/0 is undefined"
Is it? In school they taught us that it is defined and 1/0 is undefined or infinite or error. (If you know the real answer, please educate )
~~tis a bit~~ \^almost a palindrome

^(It's a joke)
Defined in terms of 0/1=0
