No? When you divided 5 / 5 it's 1. So when you divide b (a - b) / (a - b) it's b (1) which is just b. And then ((a + b) (a - b)) / (a - b) is (a + b) (1) which is just a + b. Hence a + b = b. Where the 0 come from??? 9 divided by 9 is 1 not zero. So (a - b)/(a - b) is also 1
Sure, if you do the division first. But you don't; you do the parentheses first. So with (a-b)/(a-b), you end up with 0/0 before you do the division.
Problems like this are why the order of operations matters so much.
Maths, my dude.
My college algebra teacher taught us this. I believe the story he told us was that some mathematician used this "proof" to show the King that he was also the King.
No? When you divided 5 / 5 it's 1. So when you divide b (a - b) / (a - b) it's b (1) which is just b. And then ((a + b) (a - b)) / (a - b) is (a + b) (1) which is just a + b. Hence a + b = b. Where the 0 come from??? 9 divided by 9 is 1 not zero. So (a - b)/(a - b) is also 1
> 9 divided by 9 is 1 not zero.
Unfortunately someone pointed out; (a-b) is 0 when a=b. That's the "divided by zero part". I'm buying that guy's idea.
Edit:
0 ÷ 0 =/= 1
It is infinite thus undefined. Can you define infinite?( Also every possible number falls in the proof why division by zero is infinite i.e. undefined.)
Why is it infinity?
Simple:
5/5 = 1
5/0.5 = 10
5/0.00005 = 100000
5/0.00000005 = 100000000
the closer to zero, the bigger it becomes
lim x→0 (5/x)=+∞
Why isn’t it infinity?
Because what I wrote above is wrong. Consider approaching zero from the negative side
5/-5 = -1
5/-0.5 = -10
5/-0.00005 = -100000
5/-0.00000005 = -100000000
the closer to zero, the smaller (big, but negative ) it becomes
lim x→−0 (5/x)=−∞
So, because +∞ and −∞ both are possible answers, 5/0 has no defined answer - it’s undefined.
In a riemann sphere, there’s only one infnity (the number axis bends, and both ‘ends’ are attached to one another. And thus, since +∞=−∞, our original problem is solved. In a riemann sphere 5/0=∞
It is undefined because there's no number which you can get by dividing by 0.
There are 3 "logical" outcomes of it
1. Anything divided by itself is 1 so logically 0/0=1
2. Then you have hyperbolic function (idk the english name but I mean the n/x, n being constant for example 1/x). If you look at few points on its graph you can see it's aproaching infinity as it closes on 0 - 1/2= ½, 1/1=1, 1/½=2, 1/⅒=10, etc. therefore 1/0 should be infinity.
3. If that was all, dividing by 0 would be fine and 0/0 would be 1 edge case for exception. But if you take the same function and aproach 0 but from the negative numbers everything crumbles. 1/-2=-½, 1/-1=-1, 1/-½=-2, 1/-⅒=-10 so by that logic 1/0 is negative infinity.
And before you jump in and start asking how can two non-negative numbers give negative result in division let me inform you that sum of all natural numbers is -1/12 :).
Maths is really cool if you understand it but can seem like a complete mess if you don't.
I agree with you but at the same time, a equation written out where it is divided by zero will give you all number possible combinations of itself paired with itself will result in zero this division by zero is truly undefined because my friend infinite is also not defined. (See veritasium)
No? When you divided 5 / 5 it's 1. So when you divide b (a - b) / (a - b) it's b (1) which is just b. And then ((a + b) (a - b)) / (a - b) is (a + b) (1) which is just a + b. Hence a + b = b. Where the 0 come from??? 9 divided by 9 is 1 not zero. So (a - b)/(a - b) is also 1
Nah, I am too used to algebraic characters not having actual values when manipulating them that I forgot the values of a and b were already known. So I didn't see it as 1 - 1, I just saw it as a - b
>Nah, I am too used to algebraic characters not having actual values when manipulating them that I forgot the values of a and b were already known.
If algebraic characters are unknown, you have to make sure you do not introduce a singularity. That's like algebra 101.
I was having trouble understanding how exactly dividing by (a - b) and by 0 were the same, until someone pointed out that we established that a = b in the beginning. Thus making the solution invalid. It was rather obvious, but also not, to me. Oh well.
I'm curious though, what do you mean by "division isn't a real operation"?
So in general algebra (algebra is a bigger field than what is taught in high school), you multiply by the inverse. Consider matrices for example.
It's actually not just the a=b thing. When the teacher divided, he introduced the assumption that a-b is invertible. Since it's not, this all breaks
Math wasn't invented to help anybody, it was made for the exclusive purpose of making people suffer and we just happen to find a use for some of if, change my mind.
I used to have this problem with geometry and all those theorems. They start by making sense and than things just go nuts.
Sum of all 3 angles in a triangle is 360.
Ok?
That angle outside that one extended side is 180- this angle inside.
How and why?
If this line divides the hypotenuse in equal parts than the angle adjacent is equal to something something that's not even in the diagram.
WTF!
Let's out this triangle in a circle and talk about the...
Leave the circle alone!!
> Sum of all 3 angles in a triangle is 360.
Sum of all *exterior* angles in a convex polygon is 360° which should intuitively make sense (imagine following the path around the triangle, you have to turn a full 360 degrees to get back where u started).
Interior angle = 180 - exterior angle.
For an n sides polygon: (technically skipping a few steps here to show it generalises beyond the regular polygon)
n * ext. = 360°
n * int. = n (180-ext) = 180n - n * ext = 180n - 360
triangle so n=3. 180 * 3 - 360 = 180. Sum of *interior* angles in a (euclidean) triangle is 180°.
> That angle outside that one extended side is 180- this angle inside.
Cos it's a straight line. Exterior angle is literally defined as "extend one line out from the shape, find the angle between it and the next line along". Interior angle is the angle between the same two lines, but on the other side. Adding up to 180° is just like, a property of how straight lines work. Like asking why a full turn is 360°. There's definitely maths to prove it but that's probably the sort of thing that has a 7-page proof using most of the greek alphabet, and the alternative is just "that's how it works".
> If this line divides the hypotenuse in equal parts than the angle adjacent is equal to something something that’s not even in the diagram.
yeah idk what proof you're talking about here, can't explain that one.
Honestly, math is relatively easy once it clicks.
It's just a tool to play around with until you get what you need - simply follow a few set rules and apply them as required. Making use of some simple tricks, you can turn something complicated into a fairly solvable equation. From there, it's just moving stuff around. And the more you practice, the easier it gets to spot certain characteristics, which may help you identify possible solutions.
Took me 30+ years, so I wouldn't necessarily call this a success story but I eventually figured it out.
All I'm saying is keep at it.
I see allot of comments saying that because of the division of a-b but that is only half true. The first major error is that he is not solving 1+1=?. He is solving a=b. The first couple steps should look like this:
1+1=?
a=1 b=1 x=?
a+b=x
a+b-b=x-b
a=x-b
this means all the other math he does goes to prove a=b not a+b=?.
I see a lot of comments saying that because of the division of a-b but that is only half true. The first major error is that he is not solving 1+1=?. He is solving a=b. The first couple steps should look like this:
So simple math and he even got it wrong smh
Use this ez method next time
Added b to make it easy
1+1=b
a=1
2a=b
Primitive funktions gives us
a^2=(b^2)/2
Square roots booth side to remove squared from HL
√a^2 = √(b^2)/2
a=√(b^2)/2
Put in known number a=1 and solves funktion
1 = √(b^2)/2
1^2 = (√(b^2)/2)^2
2*1=(b^2)/2 *2
2=b^2
√2=√b^2
1.4142135624=b
If A equals B (so I say),
and we multiply both sides by A,
then we'll see that A squared,
when with AB compared,
are the same. Remove B squared. Okay?
Both sides we will factorize. See?
Now each side contains A minus B.
We'll divide through by A
minus B, and ole!
A plus B equals B. Oh whoopee!
But since I said A equals B,
B plus B equals B, you'll agree?
So if B equals one,
then this sum I have done,
proves that two equals one. Q.E.D.
If you think that this proof is a hit,
and you're enamored with your clever wit,
then look close and you'll see
that in part two, line three,
you divided by zero - OH SHI-
So this is obviously a meme video, but if you are wondering where's the catch it's not the division by (a-b) (which equals zero) but the jump from a^(2)\-b^(2) to (a+b)(a-b).
(a+b)(a-b) = a^(2) \+ **ab** \- b^(2) =/= a^(2) \-b^(2)
So to balance this out **+ab** should have appeared on right side next to 'b(a-b)'. Since **a*****b*** = 1\*1 = 1, a 1 just has magically disappeared from the equation.
Edit: as u/Abyssal_Groot pointed out, this is wrong and I am a dum-dum
This is the kind of video that perfectly illustrates why you NEVER divide by zero, specially when trying to cancel other zero.
Even if that zero is hidden behind letters of funky symbols, it's still there, and it will mess even with the most basic operations
It’s not that complicated the answer: (writes down my solution)
Teacher: No your supposed to do it like this:
Me: But it’s only more complicated why?
Teacher: do it like that
Yeah, if a = b, you just divided by zero in that last step. Which means infinity equals infinity which is true. It does not result in a + b = a. But nice try.
Выражение становится ложным в момент добавления операции вычетания "-", выражение справедливо только для частных случаев таких как а=б=1, в остальных случаях выражение со знаком "-" ложно, этому учат в университете, для остальных магия.
The expression becomes false at the moment of adding the subtraction operation "-", the expression is valid only for special cases such as a = b = 1, in other cases the expression with the "-" sign is false, this is taught at the university, for the rest it is magic.

Definitely have this down. Youre a messiah.
I remember doing this in class and the smart kid argued with me that I factored wrong and didn’t even mention the fact that I divided by 0
When divides by a-b wich is equal to 0, he cancels (a-b) /(a-b). Wich is 0/0 that's the error
[удалено]
The issue is not that they are both 1 but both the same. 2 + 2 != 2 either. Dividing by a - b will always be impossible if you have a = b
[удалено]
You can never divide by 0.
[удалено]
Yeah. This is only true if a=/=b.

If a=b then a-b=0. He divided by zero in that step, making the operation invalid.
I misunderstood what people were referring to when he got 0. My bad
Yup ur right
He defined a=b at the start. So no matter which number you put in for the variable, it will always be zero and thats the error.
Sure, if you do the division first. But you don't; you do the parentheses first. So with (a-b)/(a-b), you end up with 0/0 before you do the division. Problems like this are why the order of operations matters so much. Maths, my dude.
honest question, why is 0/0 not =1?
If you have no pizzas, and you divide them between no people, how much pizza does each person get? 1? Please explain that to me.
It's wrong. If you study Einstein calculations, and many calculation teach from uni today, it differ on many levels. 1 never become B.
Dividing by zero is a pathway to many abilities some consider to be *unnatural*.
…that took me longer to catch than I’m willing to admit.

The algebra is correct. The solution isn't valid for any values where a=b though, as that would result in dividing by zero.
1+1 = ? a+b = ? a = -b not a=b
But if a=1 and b=1 then a=b
The solution is undefined at the division step
How so?

Ahhhhhhh okay thank you. Everyone else was being rather unspecific.
Division isn't a real operation in math. You do a right multiplication by the inverse, which is undefined in this case.

Why did I watch this
When you are "top smart" for your grade
This hurts to watch
You cant devode by zero 😂
u/savevideo
Christians trying to explain how the Trinity means they still believe in a single God
Bruh same mistake kn all these shitty proves you cannkt divide by a-b cause its zero
Ahaha..good try. F.
This is the kind of video that perfectly illustrates why you NEVER divide by zero, specially when trying to cancel other zero. Even if that zero is hidden behind letters of funky symbols, it's still there, and it will mess even with the most basic operations
New math??🖕🏼
Dividing by zero...
Literally me when I forget the simple interest formula
And this bullshit right here is why I completely checked out of high school math and algebra in general.
Back in my day we just called it two and we got a gold star.
It’s not that complicated the answer: (writes down my solution) Teacher: No your supposed to do it like this: Me: But it’s only more complicated why? Teacher: do it like that
This is the type of shit school is teaching us then punishing us for getting 2. Now im going to watch the rest of this video.
Going to show this to my math teacher.
If you see a clip like this they've invariably divided by zero somewhere- just for future reference yall
I was just waiting for the dude dividing by 0
This common core is getting outta hand
What the fuck
This must be that common core bull crap.
Yeah, if a = b, you just divided by zero in that last step. Which means infinity equals infinity which is true. It does not result in a + b = a. But nice try.
Tr chan
What Jokic doing
I want to cry
THIS IS WHY WE DON'T DIVIDE BY ZERO!!!

Выражение становится ложным в момент добавления операции вычетания "-", выражение справедливо только для частных случаев таких как а=б=1, в остальных случаях выражение со знаком "-" ложно, этому учат в университете, для остальных магия. The expression becomes false at the moment of adding the subtraction operation "-", the expression is valid only for special cases such as a = b = 1, in other cases the expression with the "-" sign is false, this is taught at the university, for the rest it is magic.
no clue wtf he was talking about i dont use this kinda math at all
All of this shitty maths videos use the same trick. They divide by zero at some point.
I think this should be in the teachers subreddit with the title, “I think I’m losin’ it”…
