Holy Hel.... Thank you for giving an answer to an ultimately unimportant question that has bothered me for a very long time.
If you divide 2 zero times it's 2..
If you divide 2 one time it's 1..
They just effed up when they came up with the terms =p
Like I guarantee you if I said I was going to divide your head one time you wouldn't let me do it 😉
Our numerical system is almost perfect but it does have it’s flaws in that certain things can not be expressed in this mathematical language, such as 1/3 as a number or percentage. Even though 1/3 exists perfectly as a fraction, it simply cannot be expressed as a percentage or as a number.
@@MattWarbThat's just because of the way our system is formatted.
This is so incredibly dumb. Infinity isn’t a NUMBER. You can’t get “close” to infinity. Infinity is a concept. Jesus Christ.

Just one thing undefined is different than impossible hes talking about limits but limits never reach the number x is aproaching so no 1:0 does not exist because the limit 1:0+ is different than the limit of 1:0- but because simply dividing something by zero does not have a meaning.
@@jpzulu4610 I mean doing the process of calculating a limit that approches infinity shows that there is an asymptote at that x value so 1/0 doesn't exist because for 1/x when x=0 is undefined due to an asymptote correct?
@@ethannorton564 not really cuz when u do a limit is when x aproaches a number so what the limit says is for example that one divided by 0.(0)1 which is 0.000000...1( the zeros are infinite) equals infinite and if its negative -infinite but it never reaches the number exactly 0. the limit when x tends to 0 doesnt exist for that reason cuz aproaching to 0 from numbers that are negative gives a different outcome compared to aproach 0 from positive numbers but simply 1/0 is a different story cuz simply it doesnt make sense dividing something by 0 u see whats the meaning of dividing a cake in 0 slices. its impossible. so limits are not the reason why theres no 1/0. This guys are making a mess thats not how u prove that 1/0 cant exist but even teachers do it
@@jpzulu4610 @JP zulu we're saying the same thing because if you plot out y= 1/x and you describe the limit as x -> 0+ does the same exact behavior as he's describing that proves that 1/0 doesn't exist cause there's an asymptote at x= 0. Not saying that it can exist. The process of taking small steps towards any number is defined as a limit so your basically contradicting yourself here saying there's no point in taking a limit when that's exactly what your doing

So why can it be when you divide by zero with a positive number it's positive infinity but when it's negative it's negative infinity
@@levi_ellis so the function is 1/x if x = 0.001 then it's 1/0.001 which equals 1000 but if x = -0.001 it's 1/-0.001 instead which is equal to -1000
@@levi_ellis dividing by 0 doesn't make infinity. it simply does not exist. it's not possible.
im not trying to say i perfectly understand it, cause i dont. but i am pretty sure.
@@levi_ellis That's kind of the whole point. If you try to divide by 0 by decreasing to it from a positive number, it'd blow up to positive infinity.
Try to divide by 0 by increasing from a negative number, and there'll be a negative sign on your fraction and it'll be negative infinity.
When numbers *are* defined, then when you do this whole thing, you should get the same number no matter which direction you come to the point from. The directions disagree for 1/0, and that's why it's undefined.
Holy shit he answered the question no university professor was able to simplify to me without fumbling and making some dumb shit up all my entire life. Hell yeah
I grew up in another country and we weren't allowed to use calculators. so I had no idea what a graphing calculator looked like, let alone understand its nuances. but because we essentially learn mathes and sciences 101+102 in highschool we'd go through all types of existentialist questions regarding the utility of methods and instrumentations in these fields. especially cz innovation is so fast in the life sciences.

If your university professor didn't know how to explain limits, you must have been taking Algebra 1 or some shit in college.
bro in what kind of university are you going? this shit is learned in middle school in my country
bruh this is what u learn in high school and its rly not difficult to grasp
Since “a/b = c because a - (b*c) = 0”, theoretically the only problem with division by 0 is that you have to subtract 0 positively infinite times from a. So I think positive infinity is the way to go.

One math teacher I had explained this matter to me & my class in the same way this guy did. He was also in the army, was super patient, and could always explain how a certain thing we're learning will be used in jobs irl, no matter what it was. I was blessed with always having good math teachers.
The best explanation I ever heard basically asked you how to reverse the operation.
Let 1 / 0 = x where x is defined.
Solve for 1.
1 = x * 0
What multiplied by 0 is 1? The answer is nothing - this is the "zero property of multiplication." That is, any number multiplied by 0 is 0, so there there is no number that x can be.
Thank you! at last a reasonable explanation!!

0s just a place holder for nothing so it would be undefined like you said
Also, the x value will never reach 0, no matter what. A function containing a fraction with a variable in it cannot equal 0.
Haha, the slight nodding towards the end. Great video
Good Lord. Math isn't one of my strong subjects but this I followed this explanation 100%. I can't believe someone explained something so clearly in 90 seconds
Yeah and it's the wrong explaination since that's a consequence and not the reason. No need for fancy stuff, just think of the basic meaning of dividing. 1:0 means "the number which multiplied by 0 makes 1", which of course doesn't exist, since anything ×0 equals 0.
Calculus is when math really starts to make sense
@@alwaysnunya5036 yeah but the calculus-ish explaination would have to use the definition of continuity and derivative, you show the derivative isn't continuous in 0 and that its upper and lower limit differ similarly to him, but while doing that you alredy had to study the domain where you say that x cant be 0 because you cant divide by zero for the aformentioned reason, so you still had to say it even before the demonstration rendering it useless. Calculus, as basics of mathematical analysis, is itself based on algebra, which is just the arithmetic of unknown numbers, where you formalize the rule you just learned by experience. And that would literally be learning that 1/0 is impossible because it's like saying 1/0=x -> 1=x*0 -> 1=0 which is obviously false, whichever number you substitute to 1.

You can’t divide by 0. If you have 6 cookies, and split it amongst 2 people, each person gets 3 cookies. If you don’t share those 6 cookies, you get 6 cookies. If you share it with no one (not even you), that’s impossible, because that would mean it never existed. The guy in the video may be right, but this is why it’s undefined.
Theory: It’s undefined because it depends on what you’re dividing on. Ex: 6/0 vs 8/0.

If you define 1/0 as the limit as x approaches 0 of abs(1/x), then 1/0 does = infinity. Similarly, -infinity = limit as x approaches 0 of -abs(1/x). This same trick is used when defining the delta function.
Clearly the result is an imaginary or hollow number, on a graph in which the first line is blue and the second is red, this imaginary number would be represented as a single purple line stretching infinitely in either direction. As such this numerical solution is called "Hollow Purple"
It sounds like he’s progressively getting more excited and giddy as he’s getting to the explanation. I appreciate that!

If jack was in math class instead of first class
The reason numbers cant be divided by 0 was explained to me like this.
Any equasion can be reversed such that each element within that equasion has an exact X-value. 0 can never be the dividend because x0=0 is true for all X-values, so x/0 is unable to uave an exact value for one of the equasions elements.
