Ahmet aa21 minute ago1/0 is not undefined. its infinty

Liliana Sanroman21 minute agoby definition 3 times 5 is 5+5+5 never 3+3+3+3+3... WRONG. Then, I can distribute 1 (thing) to 2 persons (1/2) which correspond a half... i can distribute 1 to nobody, i still have 1 (it is not infinite) yea yea yea, i want to distribute it but none to recibe it, i keep it to my own i still have 1... think about it.

B Pettis23 minutes agoAwesome teacher. What's even better ..... I can understand him. Had 4 teachers in my college career where I had to decipher/translate their speech so that I could learn the subject.

Though my high school algebra teacher has been the best teacher I've known. He made the class full ... made it relevant ... was animated....

Love to take a class from this guy.

Had 1 professor that during his lectures, nearly read from the text, if you asked a question he read from the text, and if you asked the same question more than once he'd get all perturbed and then not answer it. Go see the TA ....

The best college professor I had was the chemistry professor. Man was disheveled and seemingly absent minded. Came to class with jumble of paper and overheads. Class was given from multitude of his copious notes. Never once opened the book. But damn if his examples made more sense than the text. If you asked a question he answered it. If someone else asked the same question he acknowledged that and then answered it in a different manner different example or a real life example etc.

Brennen AkelyHour agoThis broke my brain

DLC ENERGY2 hours agook, but... it's still infinity. infinity is a unique concept beyond numbers. you can't add to it. and negative infinity is its own answer too. you need both logical answers for boolean reasons. nothing is less than negative infinity. nothing is greater than positive infinity. this completely follows rules of logic. infinity is perfect when it comes to dividing by 0 in programming. it fills in the logic for you. no having to explicitly make if statements. let the comparators rule. (1/0 > anything) vs (1 > anything x 0) LOGIC!

LennyTheChicken -_-3 hours agoI love the energy un this guy. He seems like he really loves math and wants to teach instead of feeling obligated to do so. I hope you have a great day Eddie!

Morgan Norris3 hours agoI think that possibly the answer to why using 0 results in undefined is because it simply already breaks the rules of math. It is neither positive or negative. It has only one factor (Ik 1 is like that but still). It’s is a complete outlier in math. Of all the numbers kids commonly know, it is the only one that we don’t Inherently know, like 1,2,3,4,5... which we don’t have to be thought to at least understand these numbers(such as the 1 is not equal to 2 example in this video) it took thousands of years of civilizations for a single civilization to come up with it. Think of all the great Greek mathematicians who never thought of it. Zero is simply a weird number with completely abnormal principles in math, which I think is why it results in complex problems like this and 0 to the 0th power and so forth

Aidan Smyth8 hours agoI feel that you can't use infinity in the equations as it is not a number, there are an infinite amount of infinities (eg. Even numbers and multiple of 3) therefore 1/inf is 2x greater than 2/inf. Infinity is not a fixed number.

LODIELIE B9 hours agoI wish he was my teacher (;

Do Hoeijmans9 hours agoInfinity can be mathematicaly treated as a unique number if you accept negative Infinity and positive Infinity are the same.

vlad quetes10 hours agoI'm not really into math but I understood it all and I found your presentation catchy and your reasoning fascinating. these are 9 minutes I won't consider wasted. you remind me of a good friend of mine whose most striking trait was that he spoke like a book. you are the kind of people who elevate teaching to its original highness.

Sand HunterPl10 hours agoWelp, pretty obvious to me as engineer university student, but still it's nice somebody shows the basics to the others in easy to understand way

Lex Slort AKA 1HitBurn10 hours ago^{+3}I don't really understand the point with 1/0 = inf = 2/0

I mean the same can be said over 1 x 0 = 0 = 2 x 0

But that also doesnt mean 1 = 2.

Just as 1/0 = inf = 2/0 doesn't necessarily mean 1=2 right?

And also the way i always look at this problem is like this:

a / b = c, so

b x c = a. so if we take:

a = 5, b = 0, c = X

Then we get:

5/0 = X

0 x X = 5

And its impossible that something times 0 becomes something else then 0.

Krauser Maou36 minutes agoLex Slort AKA 1HitBurn

If it'll never be a/b=c or, a=b x c if a=5(okay) while b=0(not zero) and c=?...

kapil busawah15 hours agoIt looks undefined cuz its every possible answer and none at all simultaneously which cannot make sense.

In quantum physics that's the only thing that does make sense. Defining 1/x where x approaches 0 would be seminal to all sciences

Shitty math rules

tigerboy196617 hours agoI used to teach Eng Lit and had to substitute in a y10 (15 year-olds) top set Maths class. I asked them what 1/0 was and all 30 of them went for their calculators.

Littleoak 1217 hours ago1/0 = infinity (multiply by 0 both sides)

1 = infinity * 0

If 0n = 0 then

1 = 0

So 1/0 != Infinity

A.K.A 0 is broken math plz fix

Albert Dela CruzDay agoIs infinity standard? Can't we label infinity like (1)infinity or (2)infinity so that we know where that infinity originated from? So we know infinity are all the same infinity (maybe we don't) but at least we know where they originated so that 1 won't be equal to 2?

No, I am just joking. Hahahahaha.

fofo cruzDay agoare u asian or british

ImLiLDude _Day agoWhy are my teachers not like this guy?

NigellDay agohate math but this video was hella interesting lol

Luis SánchezDay agoQuick question. We should be able to create a number to represent 1/0 without solving it the same way we created i to represent the square root of -1, shouldn't we?

Let's call that number, say, j. 2/0 would simply be 2j, which is different from 1j.

Daniel von BoseDay agoIf a/b = c, this is equivalent to saying a = bc. If b is zero bc is always zero and can never equal a unless a is also zero. But 0/0 is indeterminate since anything times zero is zero. c the answer to the division problem is anything!

caleb williamsDay ago5:16 aren't there multiple sizes of infinity though? wouldn't it be better to say that 1/0= 1infinity and 2/0=2infinity?

William WangDay agoYou realise you waste 9 minutes of your life if you already took calculus...

Bill LeeDay agoThe concept of "infinity" is not a number, finite or otherwise. Therefore you cannot equate anything to "infinity", rather you can only approach infinity.

Pravin DahalDay agoNo, this is not what division is and that is not why it's undefined. God! It's right there in the name. "Division", meaning dividing something.

Divide 100 into 4 parts. That would be 25 each.

Divide 100 into 2 parts. 50 each.

Divide 100 into 1 part. That's already 1 part, so 100 it is.

Divide 100 into 0 parts. 100 is already 1 part. I can't divide it into zero parts. Wtf? That doesn't make any sense.

That is why it's undefined.

Mathematics is a way to model reality, not reality itself. Don't ever forget that part and you won't get sucked into retarded nonsense like Banach-Tarski paradox or waste your time on simple ideas like "divide by zero".

razeDay agobut then, what's 0divided by 0?????

0-0=0!

zdrastvutyeDay ago5:40 1=2 means the intersection of y=x+1 and y=x+2 which calculates x+1=x+2 but this intersection does not exist

Roger AhierDay agoDividing by 0 is nothing more than adding another axis to the equation.

Ap ADay agothis is how religions came into existence, via fake logic, smart guy and really stupid audience.

Miki BrunnerDay agoI believe the problem is that the set of math-rules we call algebra is not enough to properly work with entities like zeroes and infinity. First we would need to recognize that there can be positive or negative 0. Simply to recognize this as property of any number to be positive or negative. Now that we fixed the problem with 0 lets focus on infinity. There is no one single infinity. Infinity + 1 is not just infinity. That increment must be taken into account on some level, other vice the math falls apart. Let's say 10/∞ is not quite the same as 1000/∞ . Yes in the end the end product may be the same but the infinity destroys the concept of division since it is not commutable operation. You cannot restore the original values once you have "∞" or "0" in place. If we had apparatus to preserve the original components of any formula - we could well work with division by 0. Imagine (10/0 = 10∞, 10∞*0 = 10) (2/0 = 2∞; 1/0 = ∞ >> 2∞ ∞). (1/-0.1 = -10; 1/-0 = -∞; -∞ ∞ 2∞ ) Would that work for you?

Cars ManiacDay ago^{+2}I want a teacher like him. It’s very interesting and he is very good to explain to students how it works 😁. With this teacher it’s funny to learn mathematics but in France ( I live in France ), you don’t want to go to school because every teachers are boring, I swear, you want to sleep. 👍

Ryan MyaDay agoLike matter and anti matter

I AM AMAZED

😍😍😍😍😍😍😍😍😍

Why can't I get a teacher like u persoally .....

EthanDay agothe 1=2 thing isn't what you'd get though? 1/0 doesn't equal 2/0 - you have to multiply both sides by 0 first and you'd get 0=0

Music OldiesDay agoEddie Woo: I disagree with any number divided by zero being infinity. Here's my take on this matter: Any number being divided into (let's say "3" in this case) always gets apportioned exactly into it's divisor, which in all but one case represents "a quantity" - however small that quantity is. To state the obvious: the smaller the quantity, the greater the quotient that gets apportioned to each quantity amount, the sum of which obviously equals the dividend (the original number being divided into). Now, the total amount of fractional numbers below the value of "1" are obviously infinite, so the smaller that fraction, the greater the number which will continue to approach infinity, as you correctly stated in your lecture. "Infinity" is just a concept describing the whole process I mentioned above, but it does not represent any "number". Next, let's take the digit "0". "Zero" represents a non-quantity, so the dividend can't be split up in any way, shape or form into this non-quantity, so to me the correct answer to "what is 3 divided by 0" should be 3, because the dividend comes out as the whole number it started out with - being that it can't be apportioned into the non-quantity, so it remains as the number it was before the equation process.

thrash metalDay agoI actually got on TheXvid because I wanted to look for exercises to improve my picking e speed at guitar... Now my brain is so fucked I don't even know how to hold my guitar

D25 GenDay agoWell, take no offence but your understanding about -infinite is wrong. -0.000001........ comes to be 0, which is neither + nor -. So it is not -infinite. I loved the way you explained/taught things. Keep up the good work.

SqueeksDay agoImo ÷0 should be the same as x0 aka 0

It works out if you use the apple tree worded variant...

15 apples on a tree, 3 people pick them equally, how many does each person have: 5

15 apples on a tree, 0 people pick them equally, how many does each person have: 0

Nobody picking so nobody will have any = 0

Multiply ?×0=0

If division is a mirror like repetitive addition/subtraction then surely

Divide ?÷0=0

Or to take your undefined

○○ + -○○ = 0

(On cell so no infinity icon)

Negating both the positive and negative infinity ends of the divisional constraints against the other, comes to a middle number that is definable and works for multiplication...

That number, obviously ZERO = 0

graham grasdalDay agothe funny thing is that right in the first minute I notice that his mind and mine are different. He thinks (3) times (5) is 5 threes and my mind says (3) items of 5 each.

Jussi .KarastiDay ago@4:00-> 1/0,001 ... 1/0,0001 ... and so on. Why would it ever reach zero, wouldn't there be more zeros after the "0," or "0."? Also, the quotient seems to go positively towards the infinity, whereas the denominator reaches finity. I'm no expert, so I don't know if that's a problem in the first place. And for last, you draw the hyperbola, which seems to support the idea that the quotient and denominator should both head towards pos. and neg. infinity? -rookie

MooksDay agothis teacher is so much better then all of my teachers put together x 36

Furious CommenterDay agoThere should be a math rule to 0 because for me 0 means nothing (except the 0 is after another number like 100) lets assume 0 as nothing for example... 50 divided by "nothing", you will divide 50 with nothing which will still be 50 just like the identity property in multiplication and addition

Imran SiddiquiDay agoThere is also an algebraic way to represent this that is very cool.

For example: 3/4, this is the same thing as 4x=3, as when you substitute for x it is equivalent.

Now take 1/0, and do the same thing.

0x=1

No number times zero is equal to one.

This is undefined.

SMART BOYDay agoI Don't Know, but it was not difficult for me. The fact of 1 divided by 0 is already cleared by me.

1/1 = 1

2/1 = 1+1 -> 2 answer

80/20 = 20+20+20+20 --> 4 answer

Then 1000/0 = 0+No power to reach up 1000+0+undefinable+0+Nothing = 0

(0+No power to reach up 1000+0+undefinable+0+Nothing = 0 isn't not??)

Elucified2 days agoGotta say, Your videos are awesome..😁

Joe Duke2 days agoOR... we can surrender. When I see a result headed to infinity, that realization is the threshold of my effort, and I surrender. So to me, n/0 = Go take a break.

Jemz Peifixy2 days agoInfinity is not a number so you cannot say that 2/0=1/0 the only way you can prive that is multiplying both sides with 0 to cancel the 0 and every number multiplied with 0 is 0 so 0=0

Two Games2 days ago^{+1}wait, so 1 + (-1) = 0 so ∞ + (-∞ ) = 0 ?

KanashimiDay agoNo. Infinity is NOT a number, and it is ALWAYS uncountable.

GavroluxDay agoInfinity is just a big number that's usually uncountable like 833763365553829292922922928282828828282828282 etc'

Two GamesDay agoThanks...

KanashimiDay agoNo. Infinity is not a number. It doesn't have a value. It's only a concept, so you simply cannot use it like that.

Hot_Daniel032 days agoInfinity is an expression of an expressionless number

BluBlu2 days agothe problem with dividing by zero is that you can create multiples Infinitys, I mean 1/0 = infinity and 2/0 = infinity too but if you have both in the same table (1/0 and 2/0) they are not equal that means that 1/0 = infinity and 2/0 = infinity'

This means that infinity it's a irrational number and 1/0 it's irrational or maybe I'm wrong and I don't understand maths. someone can confirm me if I'm wrong or right?

Josh Rick2 days agoYou are an idiot

Muduler Derpz2 days ago^{+1}Couldnt you just say its undefinable because 0 has no value. 0 Is only a "number" you write to visualize nothing.

He showed 1 and 2 are not the same by counting pens - then show us 0 pens;)

Karen Smith2 days agoThe sad part is the fact this great teacher makes a small salary. Soon, he will get hired to work for a corporation making 3x his current salary and then the education system struggles to find another great teacher.

DarconizerRC2 days agoBUT there are other math problems, that have two outcomes, like square root of 4 can be 2 or -2 ! So why not just say x divided by zero can be infinity or -infinity ?

Same is for the pq-formula where we have x1 and x2 as possibilities and only the context gives the right one. We could just do that here. Please explain !

Another thing I never understood:

x to the power of 0 is 1 - WHY ?

if the power of y means how many times x is multiplied with itself it means x^3 = x*x*x ; x^2 = x*x ; x^1 = x and logicaly it should mean x^0 is no x at all, so zero ! why is x^0 = 1 ???

Toaster Ninja2 days agoaye listen if you have a cake for example, and there is 0, which is equal to nothing, which means that no one needs the cake which means that *the* cake isn't eaten that means you will still have 1 cake left or infinity slices. I would say the basic answer would be 1 cause it's infinity slices in 1 cake
