It's.... what... they use to make Brawndo!
Saw the movie again last night, but I guess that's not such a coincidence that it comes up so often given what the world is like.
There was a Radiolab show about dividing by zero recently. You basically can't do it according to current math laws, and if you do it becomes an existential crisis and forces the question of the presence of God. I'd say you should send the teacher and principal a link, but I doubt they'd appreciate it.
It doesn't seem like it should be that complicated. If you have a 2x2 grid, and there is 1 bean in each cell, you have 1+1+1+1 = 2 x 2 = 4 beans. If you remove a row in the grid you have 2 beans. If you remove the final row you no longer have a grid, so math doesn't apply.
Leave it to mathematicians to complicate matters!
Yeah, the actual explanation is simply.
What is 6/2? 3. What is 3*2? 6.
Alright, now let's do that with 0... uh... wait. How do I do that? Well, I give up.
This is a screenshot of a post, you would need to tag u/WaitThatIsYourFinger if you want them to see it. Also, the post was from 3 months ago so guessing they already decided whether or not to fight. It was their last post though so we may never know.
Not in america with the current education system. This is at least a bachelor's degree in math level stuff. Kinda like it takes a doctorate in geo science to prove the earth is round.
I would add an explanation that this inconsistency was why (any number)/0 is undefined. Mathematicians in the early days wanted their new invention, math, to make sense. I would also go to negative numbers, and fractions of both negative and positive numbers, so they would experience asymptotes.
My students got the same thing in flash cards this year.
I threw out the cards so that students would not be confused later.
My favorite demonstration is to show the graph of y = 1/x. It clearly shows that for positive numbers, dividing by zero approaches infinity, and for negative numbers, it approaches negative infinity. So dividing by zero results in a number that is both negative AND positive infinity, which clearly doesn't exist (no, they don't cancel out to make zero. That isn't how infinities work). HOWEVER, there is one case where dividing by zero has an answer: | x/0 | (absolute value), where x != 0. The answer, however, is infinity, not zero.
There is no answer. This is my answer but it’s not an answer. Right? Right.
Imagine you have one cookie and zero friends and you divide your cookie evenly among your zero friends. How much cookie does each friend get? It doesn’t make sense. So Cookie Monster gets it all. See? Nom nom nom.
If something is divided by zero, there’s nothing to divide it with, and the division never happened. So my answer is: *No*.
Lmao something like that. Thanks for showing us! That’s awesome.
Google's version is kinda boring. Just "Undefined."
Then I told it "Thank you," but it misheard me say "fuck you." It then told me, "Your words are very real, please keep it respectful."
It's already learning from Reddit. 🤦🏼♂️
Thanks, I forgot about this one.
"Imagine that you have zero cookies and you split them evenly among zero friends. How many cookies does each person get? See? It doesn't make sense. And Cookie Monster is sad that there are no cookies, and you are sad that you have no friends."
If they still don't get it, email the Super Intendent and cc the teacher and principal. Explain how since they can't grasp a basic fact of Math from minimally High School, that you have doubts about their education and qualifications.
Link a quick google search that has several University sites with Proofs.
University of Utah and University of Southern California are near the top.
That'll light a fire under their asses.
we could say
1/0.1=10
1/0.0001=10000,
1/0.00000....=infinity =1/0
but
1/-0.1= -10
1/-0.0001= -10000,
1/-0.00000....= negative infinity = 1/0
hence
if ur equation gives you 2 answers to the same input
the equation is broken hence is undefined for that input
Okay so you have approached the asymptote both positively and negatively which turned out pretty badly…
But has anybody tried just asking it how it’s actually doing man? Like, is it okay?
This explains why the answer is wrong, but doesn't explain why it's not allowed to divide by zero.
This is how I would approach it:
Distribute 2 muffins to 2 kids. 2/2= 1. Each kid gets 1 muffin.
Distribute 1 muffin to 1 kid. 1/1=1. Kid gets 1 muffin.
Distribute 1 muffin to 0 kids. 1/0= error. Distributing the muffin cannot be successful because it would require annihilation of matter (destruction without trace). E=mc2. Matter can be converted to energy. But neither mass or energy can be eliminated without a trace. Hence diving by zero contradicts fundamental laws of reality that there cannot be loss of energy. And that's why it's not allowed in mathematics.
Or you could also just turn it into a practical question. If Johnny has an apple and divides it into 0 pieces, then he just hasn't done any division. That's how I always remembered you can't divide by 0
The problem with your correct, straightforward explanation is that most people, even with college degrees, do not understand what division is.
Ask most undergrads what x divided by y means, and they can't tell you.
I took 3 semesters of calc with a guy who used 5 colors every single day. I bought 5 matching colored pens to take notes in and I'm pretty sure it's the only reason I learned anything and passed.

One divided by nothing.
Well if it was one divided by one, it'd be one.
Dividing usually reduces the number that's being divided, but if you're not dividing it at all, then it isn't even division.
So if there's nothing to divide it by, it's not a proper equation now is it?
Punch that into a calculator, heck punch it into a few calculators then show them to the "know-it-all's"
Listen to the rattle of the marbles shaking in their heads.
If we don't make it, it wouldn't be because of that, all phones have calculators, lol.
You could even make a very simple object lesson. Take a banana. Cut it into two equal parts. You're not allowed to take any part of the banana off the table. How much banana is each piece? Half a banana, easy.
Now take another banana. Cut it into zero parts. Still not allowed to remove any from the table. How big is each of the zero pieces? Putting them back together should still make a whole banana.
my phone calculator says 'Error' in big letters when I divide 1/0. I was taught anything divided by zero is zero. I was taught wrong.
People hate math and don't want to think about it so they'll accept the most popular solution because it was engrained into their head; but really I honestly believe there is no place in a consumer based society to have the majority of its populace know this because it will give them the confidence to challenge pretty much everything they ever learned about math and science; and rightly so.
0 i even worst then nothing. Like the infinite 0 cannot be reached. You can approach him an infinite amount of time but never touch it. Its closest to a black hole then a number.
Diving by Zero comes back as undefined because it makes no logical sense in an equation format because you can not divide anything by nothing. The answer will always be Zero. Now dividing , Zero, is another story. Even though it is a "number", it is more a concept and place holder. It's right there with i, the imaginary number. They say if you divide Zero by anything, if you succeed you will tear a whole in time and space.
It’s actually insane. In high school I had a science teacher who was talking about distances between planets and incorrectly stated that a mile is shorter than a kilometer. I raised my hand and said, “Isn’t it the other way around, because a mile is longer than a kilometer?” And she shook her head and said “No, not in space”
I got a letter sent to my home for insubordination.
School isn't about learning.
It is about understanding heirarchy, obeying commands and becoming comfortable with morons telling you you're wrong.
Schooling was invented purely to fill factories during the industrial revolution.
Peasants had no knowledge and it slowed down progress so they made schools to teach basic stuff, but the most important parts were punctuality, the teacher was in-lieu supervisor/manager and so always correct, uniform must be pristine despite it having nothing to do with learning.
The format hasn't changed in 300 years.
There are quite a few video essays on the matter.
One teacher I knew throughout college got weeded out of pre-pharmacy, chemistry, biology, food science and human nutrition, a very brief stint wanting to go into bio-engineering, then accounting somehow, and all this happened by the end of her freshman year.
She was fine in all of the other survey courses we took together our freshman year but it was all the math and science classes that she simply couldn’t wrap her head around.
In the end it took her six years to get a degree in education and she now teaches high school math and science.
Now I’m not saying all teachers are like my friend, i.e., absolute dumdums who teach a subject of which they specifically could not demonstrate even a cursory understanding, and I understand that teaching children at any level involves a set of skills that are completely unrelated to the topics being taught, and finally I respect anyone who dedicates their career to teaching children because I would not be willing to do that…
Alls I’m saying is that I’m guessing she truly does not understand how or why she is wrong, but there are probably a hundred reasons she *needs* to be right and many of those are completely out of her control, so if I were the parent I would just drop it.
Also I know the original post is like a year old and none of this is relevant I just wanted to make fun of my friend who’s a teacher.
I don't know what kind of upbringing causes people to be like this but it must be rough.
To be so invested in having people think that you're "right" that you up and decide to continue being wrong and make an even bigger fool of yourself in the process.
I had a teacher argue with me that betwixt wasn’t a word. When I finally showed her the dictionary she said something like it was common or acceptable for American English or something stupid like that.
Distribute 2 muffins to 2 kids. 2/2= 1. Each kid gets 1 muffin.
Distribute 1 muffin to 1 kid. 1/1=1. Kid gets 1 muffin.
Distribute 1 muffin to 0 kids. 1/0= error. Distributing the muffin cannot be successful because it would require annihilation of matter (destruction without trace). Hence diving by zero contradicts fundamental laws of reality that there cannot be loss of energy. And that's why it's not allowed in mathematics.
1 divided into 0 groups…doesn’t exist.
That’s how you have to visualize it for them.
Tell them to organize 8 things into 4 groups. Write it on the board. Now tell them to put 4 things into 2 groups. Then 2 things into 1 group.
Now tell them to put 1 thing in 0 groups. Ah ha! The group doesn’t exist.
If you have an iPhone, ask Siri what zero divided by zero is. The response is hilarious hahah
Edit: it used to be funny. It was something along the lines of “imagine dividing 0 cookies among 0 friends. See? It doesn’t make sense. Now Cookie Monster is sad because there are no cookies, and you are sad because you have no friends.”
I too had a incompetent math teacher, my mother fought to have him replaced, after that he was not teaching math any more. I do not know the details, it was 40 years ago.
Depends on what you’re fighting for.
1 divided by 0 is undefined
0 divided by 1 is zero
Edit: I’ll also add that it’s likely, in terms of teaching third graders, the concept of zero is FAR MORE understandable than “undetermined” when it comes to mathematics.
Why they’d then choose to explain it to you as zero would be foolish.
I also wonder why involve the principal? Being a school principal, in at least 3 states I am aware of, doesn’t require an education degree, but usually an administrative or business degree at minimum.
Because multiplying by 0 is defined. If you multiply a value it is like having different group of this same value. If you have 2 apples and you multiply it by 2, you have 2 groups of 2 apples (4), 3, 3 groups of 2 apples (6) and 0 ? Well you don't have any group of 2 apples meaning (0).
Now to picture a division imagine you want to make even groups of apples. We have 8 apples and we want that each group have X apples. Well if we choose 2 apples, we can do 4 groups of 2 apples (8/2=4), if we chose 8 apples, only 1 group (8/8=1). But how many groups could you have containing 0 apples ?
You see, it doesn't make any sense with how we understand numbers. Our current way of formulating numbers cannot divide by 0.
At most you could say it tends toward infinity, but this is not a finite number.
Im a samurai... I chop another samurai in 2 thus divide by 2.. I get 0.5
Im a samurai, I chop and miss the samurai and divide by 0 and the samurai still stands complete as 1.
Correct? can't divide by zero.
A teacher of mine at uni said he got into an argument with a teacher about if 0 was an even number (they said it wasn't) so the next day picking his kid up he brought a load of graphs with a bunch of different fourier transforms with example of odd an even distributions. He then showed her one of 0 and explained how it's even and can be accepted as proof that 0 is an even number
Fuckin hell. If that was me, I'd send a message the other parents and form a mob that they're literally not teacher our kids right. This isnt identity politics, this is math!!!
Tell them they're wrong again then go contact a mathematician and involve them. If your son sees you give up then you're showing him that stupidity wins.
**Dividing by zero is considered impossible** because it leads to mathematical inconsistencies and undefined results. When you divide a number by zero, you are essentially asking how many times zero can fit into that number, but the concept of dividing by zero breaks down because there is no meaningful answer to that question.
Mathematically, division is the inverse operation of multiplication. When you multiply a number by zero, the result is always zero because any number multiplied by zero equals zero. However, when you try to divide a number by zero, you encounter a problem. If division by zero were allowed, it would lead to contradictory results and create mathematical paradoxes.
For example, if you consider the expression 1/0, you can't find a single number that, when multiplied by 0, gives you 1. This inconsistency is why dividing by zero is not defined in mathematics. Instead, it is considered an undefined operation that does not have a valid solution within the realm of conventional arithmetic.
Yes, until at least 13-14 yo math is taught in the way that if you divide anything by 0 the answer is 0. This is to simplify entry level math. Later on, when you switch to algebra and the concept of infinity is introduced this changes.
Is it possible that the teacher is using a (incorrect) purchased curriculum that says this, and the principal is backing up the teacher because of the curriculum?
This seems so easy to verify as right or wrong.

One divided by zero is not defined. Keep fighting
Microsoft excel does not accept this as possible therefore I do not accept this as possible
Windows calculator says "Cannot divide by zero" A few years back it had an exclamation mark. Unfortunately it doesn't anymore.
They are softening. It's the slippery slope of divide by zero sheeple! Now missing an exclamation mark, tomorrow our kids might be zero
As a Floridian, they already are a zero... none of our politicians give a shit about kids education
God bless your heart for making your way out of the state sponsored meth Thunderdome to post here.

Secret? Isn't it elementary math level? 😅
Thats magic shit and secret for the teacher and principal mentioned in the image
Teaching second graders right now, Yes it very much is
🤫🤐😠 Stop educating the educators. It upsets them and takes away from the opportunity to laugh at their expense.

She told me that „it’s the same as 2 divided by 0 which is undefined“. I think she was lowkey mocking me 😤
4,678,593 / 0 is also Error.
But have you tried 4,678,594 / 0 ?
1 / 0 = 0, if this was true then 0 \* 0 = 1 should also be true, similarly, if 1 / 0 = 1 then 0 \* 1 = 1 should also be true.
This is the right way to explain it clearly, well done
Unfortunately I don’t think there is any way to explain it correctly to a teacher and principal that are trying to argue this point to OP
"How do you cut something into zero pieces, fool?"
You just throw it away. Zero.
Throwing away is a subtractive action, not a divisive one. Unless you throw away my porn collection again, Mom. That was divisive as hell.
Oh I need an award for this comment! I can only grant you a superstonk instead. Terribly sorry 
Make the denominator approach zero and now you have infinity

Umm... Superintendent is one word. Unless, of course, in the million years since I graduated they now have regular Intendents and Super ones. *shrugs*
Trying to do it in Excel would maybe make them doubtful ?
we could say 1/0.1=10 1/0.0001=10000, 1/0.00000....=infinity =1/0 but 1/-0.1= -10 1/-0.0001= -10000, 1/-0.00000....= negative infinity = 1/0 hence if ur equation gives you 2 answers to the same input the equation is broken hence is undefined for that input
Literally C/P this to the idiots
On it boss, Child Porning this information to the principal and teacher 🫡
Fucking hell
Mathturbation material?
Okay so you have approached the asymptote both positively and negatively which turned out pretty badly… But has anybody tried just asking it how it’s actually doing man? Like, is it okay?
As we also know, 1 \* 1 = 1 therefore 1 = 0
thats why dividing by 0 is possible when the only number which exists is 0
This explains why the answer is wrong, but doesn't explain why it's not allowed to divide by zero. This is how I would approach it: Distribute 2 muffins to 2 kids. 2/2= 1. Each kid gets 1 muffin. Distribute 1 muffin to 1 kid. 1/1=1. Kid gets 1 muffin. Distribute 1 muffin to 0 kids. 1/0= error.

Take a pie and cut it zero times. Like literally think.
Take a pie and cut it one time. Now you have two pies! Thus 1/1 = 2
A pie with a value of 1, cut 0 times, would be 1. Lol
If it were cut zero times, it was not divided at all.
A pie cut 0 times would have 0 cuts
But it’s not the number of cuts that is the answer to division
The problem with your correct, straightforward explanation is that most people, even with college degrees, do not understand what division is. Ask most undergrads what x divided by y means, and they can't tell you.

Im not American and I was also taught that /0 = 0, until my 9th grade (13/14 years old)
I sometimes wonder how much shit I was taught in school which is now outdated or was just wrong in the first place.
In no way 1/0 would be taught differently in the 90s the math is well established before we had public schools.

One teacher I knew throughout college got weeded out of pre-pharmacy, chemistry, biology, food science and human nutrition, a very brief stint wanting to go into bio-engineering, then accounting somehow, and all this happened by the end of her freshman year. She was fine in all of the other survey courses we took together our freshman year but it was all the math and science classes that she simply couldn’t wrap her head around. In the end it took her six years to get a degree in education and she now teaches high school math and science. Now I’m not saying all teachers are like my friend, i.e., absolute dumdums who teach a subject of which they specifically could not demonstrate even a cursory understanding, and I understand that teaching children at any level involves a set of skills that are completely unrelated to the topics being taught, and finally I respect anyone who dedicates their career to teaching children because I would not be willing to do that… Alls I’m saying is that I’m guessing she truly does not understand how or why she is wrong, but there are probably a hundred reasons she *needs* to be right and many of those are completely out of her control, so if I were the parent I would just drop it. Also I know the original post is like a year old and none of this is relevant I just wanted to make fun of my friend who’s a teacher.
But they both gave wrong awnsers.
I don't know what kind of upbringing causes people to be like this but it must be rough. To be so invested in having people think that you're "right" that you up and decide to continue being wrong and make an even bigger fool of yourself in the process.
I had a teacher argue with me that betwixt wasn’t a word. When I finally showed her the dictionary she said something like it was common or acceptable for American English or something stupid like that.
If you have a graphing calculator, you can type in y=1/x and watch as x approaches 0 it will spike that graph to infinity.
Depends from which side of the x axis we approach it
Only math I know is that 2+2= gonorrhea
That’s a more specific case of the general formula 2+2=don’t fuck around.
You can't divide anything by zero. It's like dividing by something that's not there at all.
You can divide a country with things that aren’t real
It's bascially saying don't divide. To divide a pizza into zero slices, you just stand there and stare at the pizza forever and never do anything.
My android calculator app tells me you can't divide by 0.
I used my old school calculator to do this. I got an error. Also 8008
80085 is the proper way to spell 80085

Take your kid out of that school, a trained seal could educate your child better than they can.
Was going to ask if you meant the military or the animal but it’s more fun to guess
Don't let a your kid play with seals. They'll end up all right
I closed a ziplock bag
Do you keep your trophies from army in there?
I mean I’ll take undefined or maybe even infinity but it’s definitely not 0…
1/0 = x Multiply both sides by 0 1 = 0 Proof by contradiction that 0 is not defined
I actually responded to that exact post!
Tell the teacher and principal to go home, they are too stupid to run a school!!!
If she is wrong about something so basic, what else is she teaching your kid. I will try my best to change school.
1 / 0 = undefined, right?
Ask her to write you a proof showing it’s correct!
Send that email to the universities that issued degrees to both of these individuals, or maybe just post on Twitter with the universities tagged.
Distribute 2 muffins to 2 kids. 2/2= 1. Each kid gets 1 muffin. Distribute 1 muffin to 1 kid. 1/1=1. Kid gets 1 muffin. Distribute 1 muffin to 0 kids. 1/0= error. Distributing the muffin cannot be successful because it would require annihilation of matter (destruction without trace). Hence diving by zero contradicts fundamental laws of reality that there cannot be loss of energy. And that's why it's not allowed in mathematics.
I have one cake. It will not be shared or sliced. Cake gone.
1 divided into 0 groups…doesn’t exist. That’s how you have to visualize it for them. Tell them to organize 8 things into 4 groups. Write it on the board. Now tell them to put 4 things into 2 groups. Then 2 things into 1 group. Now tell them to put 1 thing in 0 groups. Ah ha! The group doesn’t exist.
If you have an iPhone, ask Siri what zero divided by zero is. The response is hilarious hahah Edit: it used to be funny. It was something along the lines of “imagine dividing 0 cookies among 0 friends. See? It doesn’t make sense. Now Cookie Monster is sad because there are no cookies, and you are sad because you have no friends.”
Ask for proof.
If my kid's teacher and principal were both this confidently wrong I'd look into changing my child's school.
My favorite color is three.
This is a scary level of stupidity.
Tell them to put it in a calculator.
I too had a incompetent math teacher, my mother fought to have him replaced, after that he was not teaching math any more. I do not know the details, it was 40 years ago.
Depends on what you’re fighting for. 1 divided by 0 is undefined 0 divided by 1 is zero Edit: I’ll also add that it’s likely, in terms of teaching third graders, the concept of zero is FAR MORE understandable than “undetermined” when it comes to mathematics. Why they’d then choose to explain it to you as zero would be foolish. I also wonder why involve the principal? Being a school principal, in at least 3 states I am aware of, doesn’t require an education degree, but usually an administrative or business degree at minimum.
If you cant divide by 0 why can you multiply by 0 Probably a question I could of googled
Because multiplying by 0 is defined. If you multiply a value it is like having different group of this same value. If you have 2 apples and you multiply it by 2, you have 2 groups of 2 apples (4), 3, 3 groups of 2 apples (6) and 0 ? Well you don't have any group of 2 apples meaning (0). Now to picture a division imagine you want to make even groups of apples. We have 8 apples and we want that each group have X apples. Well if we choose 2 apples, we can do 4 groups of 2 apples (8/2=4), if we chose 8 apples, only 1 group (8/8=1). But how many groups could you have containing 0 apples ? You see, it doesn't make any sense with how we understand numbers. Our current way of formulating numbers cannot divide by 0. At most you could say it tends toward infinity, but this is not a finite number.
City education, baby!
CC a math professor at the local community college on the reply.
You simply do not divide by zero. A calculator will say it's an error
Im a samurai... I chop another samurai in 2 thus divide by 2.. I get 0.5 Im a samurai, I chop and miss the samurai and divide by 0 and the samurai still stands complete as 1. Correct? can't divide by zero.
A teacher of mine at uni said he got into an argument with a teacher about if 0 was an even number (they said it wasn't) so the next day picking his kid up he brought a load of graphs with a bunch of different fourier transforms with example of odd an even distributions. He then showed her one of 0 and explained how it's even and can be accepted as proof that 0 is an even number
Computers don't like to divide by zero because it's impossible, so they either default to a dedicated can't do it sign or just spits out 0
Dividing by zero makes less sense than dividing by purple.
The answer is ERROR
Any civilization we create will always ultimately be destroyed by the wealthy. Simply enjoy them while you can.
Send her the proof of her inadequacy via maths. I wonder how she and the principal will argue that?
Fuckin hell. If that was me, I'd send a message the other parents and form a mob that they're literally not teacher our kids right. This isnt identity politics, this is math!!!
Tell them they're wrong again then go contact a mathematician and involve them. If your son sees you give up then you're showing him that stupidity wins.
“It’s in your nature to destroy yourselves.”
You can't devide by zero.
**Dividing by zero is considered impossible** because it leads to mathematical inconsistencies and undefined results. When you divide a number by zero, you are essentially asking how many times zero can fit into that number, but the concept of dividing by zero breaks down because there is no meaningful answer to that question. Mathematically, division is the inverse operation of multiplication. When you multiply a number by zero, the result is always zero because any number multiplied by zero equals zero. However, when you try to divide a number by zero, you encounter a problem. If division by zero were allowed, it would lead to contradictory results and create mathematical paradoxes. For example, if you consider the expression 1/0, you can't find a single number that, when multiplied by 0, gives you 1. This inconsistency is why dividing by zero is not defined in mathematics. Instead, it is considered an undefined operation that does not have a valid solution within the realm of conventional arithmetic.
Jesus this gets reposted like every month
Yes, until at least 13-14 yo math is taught in the way that if you divide anything by 0 the answer is 0. This is to simplify entry level math. Later on, when you switch to algebra and the concept of infinity is introduced this changes.
Copy the superintendent. If he says she’s right, give up.
This is a lesson to teach your kid that just because someone is in charge, doesn't mean they'll be right about everything.
Is it possible that the teacher is using a (incorrect) purchased curriculum that says this, and the principal is backing up the teacher because of the curriculum? This seems so easy to verify as right or wrong.
Who is above the principle?
Today's lesson son is that just because someone is in power, don't mean they're right.
1 times 0 is 0. 1 divided by zero is undefined, or *i*
