    You can think of it this way. Think of numbers like A to B, or like a path.
    1 is a path. It ends at 1.
    2 is a path. It ends at 2.
    3 is a path. It ends at 3, and so forth.
    A man walks 3 steps. How many steps has he walked? 3.
    However, infinity loops into itself. It has an *infinite* path. It doesn't end at 100, 2,000, 30,000. It ends at infinity.
    On a number line, you can slide your finger left or right. Imagine you start at 3 and move 2 to the right. You land on 5.
    But then you're asked to start on 1 and move infinity to the right.
    *Where do you move? How much do you move to the right by?*

    "Division" by zero isn't that undefinable, but I guess making rules is more paedagogic.
    Eventually the more one understands math, the more one can question authority.

    unnecessary philosophizing in mathematics
    dividing by 0 means not dividing at all
    whereas dividing bei 0,1 is just like cutting the numerator into 10 pieces

    I reckon minus infinity is the same as regular infinity as I believe it is opposite to 0 and you can’t get negative 0. I also reckon /0 could mean infinity if you don’t treat it as an integer as it is more of an expression.

    Just a question, you told that 1/0= infinity =2/0, so 1=2, what is impossible. But they can be just proporcional: 1/0×2/2 is 2/0, the same logic of 1/2×2/2=2/4. There is only one difference, which is that 0 times anything is 0

    Wait... If 1/0 is INF and -INF, so it must be INF times -INF, which thats FAR away. So it is -++-1. Which that does not exist, so 1/0 is (N.E) so 1/0 is (N.E.) which that is an ERROR. so 1/0 is an error. Job well done.

    Division is just reversed multiplication. Xx0=0 and therefore x/0=0. Put it this way, 4x4=16, and 16/4=4. See? Its just rearranged And if you switch out one of the 4's with zero it would be 16/0=0 BECAUSE 16x0=0 obviously, i switched it up a bit just to make it easier to understand, but you get the point.

  • The Bishop

    The square root of a negative number is also undefinable though surely? Yet we managed to define it as “i”. Why can’t we do the same thing to dividing by 0? Why can’t we just call it “j”, for example, and class it as another imaginary number?
    I would genuinely like to know the answer to this as I’m sure there is a solution I am just unsure to what the solution is.

    Also if you were to make it algebraic, it would be
    1 divided by 0 = x
    But 0 multiplied by anything will equal 0
    In this equation 0 is multiplied by something to equal absolutely anything, because you can replace the number with anything you want and get the same result, exactly like what the teacher spoke about. Eg 2=0x or 10=0x
    If x = infinity, then 0 times infinity equals anything.

  • SuperCityscan
    SuperCityscan 15 days ago

    Weeeeeeeeeeeeeeeeell, if division is "how many times can I substract x to make it equal to 0" then 1/-1 is infinite, because 1-(-1)=2, 2-(-1) =3 and so on.
    And because 1/0 became something and 2/0 became the same thing, that does not mean 1=2. It makes no sense for me in that context, because it does not broke the set up logic to that point. It's like 1*0=0=2*0, does that mean 1=2, NO.
    But still liked it. It would simplify for people with high school math knowledge.

    As the denominator approaches zero, the solution is defined infinitely until it reaches an asymptote where it's undefined. In other words the solution is only defined for all denominator greater or less than zero. I don't know if i understood it right😞😞

  • eriksonidingle
    eriksonidingle 23 days ago

    Hmmm. 2/0 and 1/0 is impossible because they both result in infinity and that means 2=1.
    That means that the sums 1+1+1+1...=infinity
    and 2+2+2+2...=infinity implies 1=2 aswell and are therefore not allowed?
    No more infinite sums? Disclosure, I think it is a mistake to treat 0 as a number, it is not a number more than infinity. 0 and infinity seem to be the same entity from different perspektives, from inside and outside. Treat 0 as a placeholder instead and math makes more sense.

    Kolejnym dowodem na to że nie możemy dzielić przez zero, bardziej intuicyjnym dla nie matematyków jest właśnie zapis dzielenia jako odejmowania. Odejmowanie w nieskończoność zera nie spowoduje że osiągniemy zero w równaniu 1-0-0-0-0-0....-0 =/= 0

  • nicholasp1987
    nicholasp1987 24 days ago

    If division is repeated subtraction, then you can't take anything away using nothing. Yes you could take something away from zero and end up in negative numbers, but his example of 15 - 5 - 5 - 5 = 0 would be 15 / 3, so 15 / 0 should be 15 -0 -0 -0 -0 and so on, would eventually still be 15! There is nothing to take away, so there is nothing to divide.
    So perhaps the answer to any number divided by zero, if the above rule applies that it is repeated subtraction, is that we end up with the same number we started with, which would then be equal to 15 ÷ 1. But 15 ÷ 15 is not equal to 15 - 15, where 15 ÷ 15 = 1 and 15-1-1-1-1-1-1-1-1-1-1-1-1-1-1-1 (15 1's) = 0.
    So perhaps division is not repeated subtraction.
    If you have 15 pizzas and divide them by 15 people you all have 1 each. But if you have 15 pizzas and take 1 away 15 times, then you have none.
    And any number divided by 0 will end up with the same number, just the same as a whole pizza sitting there with no one to eat it will still be whole because no one has taken a slice.
    I guess that would be how i see it, but i am not a mathematician.

  • A10戈LøLPRASAD Gaming

    Sir, what if when you got the answer 1/0 = 2/0, I do not see anything wrong with that. You straight away jumped to the conclusion without seeing that you skipped an intermediate CONCEPTUAL step. See, if I give you 1x0=2=0, then you could cut 0 out of the equation because, well, same thing on same sides so just cut it out and say 1=2, right? But no. It is equal to 0. So what I am trying to say is, when you cross-multiply the first equation, you can always get 0 and not ∞. Obviously you showed 1≠2 in a fancy way but it could have been just a simpler solution. So in the end you did not prove 1=2, you proved 0=0.
    And oh, in case you are wondering, I could have solved this by defining a limit but thats just not correct when you are looking at conceptual maths and not all the fancy stuff.

    Don't know though. Maybe I am wrong.

    Well... you forgot one thing... so we have something which goes to infinity, and negative infinity. You can clearly see on graph he have drawed that there is no touching point, which will lead us to know it is complex. So there is term called complex infinity which will fit perfectly in this term. Its notation is just like infinity but it has ~ on it.
