    1 divise 0 cant equal ìninity because ìninity x 0 not equal 1, ez

    1/0=infinity can't we say (numerator)/0=(numerator)infinity...

    Certain things that can be said :
    1. Division is repetitive subtraction, so 1/0 = 1 - ( 0+0+0... infinite times), even if 0 is subtracted infinite times from 1, the result can't be 0. So, the answer is Not possible .. or cannot be defined.
    2. When we are suggesting a pattern for 1/0 = ∞ and for 2/0 = ∞ , we can't equate the two infinities because the infinity values will be different, just like 1/0.001 = 1000 and 2/0.001 = 2000. So, again that should not violate any rule.
    Thanks for this wonderful teaching !

    If only my teacher in primary school taught me that multiplication is repeated adding and division is repeated subtraction. That's a really nice mnemonic device for kids!

    divide by 0 is 0. using both methods confirm that the result is outside the scope of infinity
    -infinity + +infinity = 0

    5:34 thats where the math left the chat room
    and hypnotism comes in
    1/0 is not the same as 2/0
    you need to multiple it crossly -> 1x0 = 2x0--->> 0=0

  • agung justika

    Why 1÷0 = ~ ,and 1÷0 = -~?
    0 is not negative number...
    1/0 = ~ = 2/0
    I take 0 = 0... 🤔
    Like this 2/3 x 3/2
    So what we do is equaling they into
    4/6 x 9/6
    So why i must take 4 = 9? Not 6 = 6?

  • Dawid Drozdz

    Answer at 3:00 is wrong - you can subtract zero from one infinitely times and still it will be one, so infinity can not be the answer. At that moment you generally proved that 1/0 does not exist.
    However, keep up the great work, you have a passion that every teacher should have! Regards!

    1=1
    5/3=1⅔
    (5/3)*3=(1⅔)*3
    5=5
    1/0=X
    (1/0)*0=X*0
    1=0

    For years I've said everything in math (as far as I've gotten anyhow) can be summed up as addition &/or subtraction with short cuts.
    I've never thought about how that'd relate to dividing by zero tho! Now I finally feel like I understand it!

    I'm a layman, high school level, but wouldn't a/0 = ax∞? Since 1/0.1 = 1x10 and 2/0.1 = 2x10.

    1 doesn’t equal 2? Stefan Banach and Alfred Tarski disagree with you!

  • K. Nickel
    K. Nickel 21 day ago

    my approach to define it is:
    there is not just one endless there are in your case 2 (think of it like there is one endless "line" going along thr way endlessly if you pair it with a second line next to it it can go endless too.
    And the negative version is nothing more than a change in direction of the line the opposite way, and you can have multiples of those... they wouldn´t even notice running in a big circle for ever.
    thats probably an answer to many unsolved questions, that it (time, space and matter) has no start (there is not one big bang... it repeats itself over and over again) and the universe is not infinite long or big. It is a ball or a sphere (like an egg, the earth the stars...) and when all matter disolves into back holes and dark matter it becomes darker and darker from the core of the ball and when the whole universe ball is dark inside in the center it gets so "dark" there is so much mass, that it bursts. and the dark matter they can´t explain is nothing else then the rest of the last "universe" therefore it can´t be detected, it is measurable but you cannot grab it. The question would then be: How many times did it happen ? In what stage are we now ? Will it ever end like life or will it transcent into something else ?
    Even when they say before the big bang there was nothing not even time...
    Its somehow true, because the blackness is so overwhealming that nothing or nobody could observe it. Probably not even god can look inside there... this is the Heisenbergsche of god, he can explain it he holds the ball, he created this ball, he is maybe the ball.
    Why do i bring god in here again... because balls like this just don´t pop up by accident... this is of a genius mind only god has.

    1/0 does not exist, no number multiplying 0 gets back to 1. Division is the inverse of multiplication.

    sorry to correct you but 1/0=infinity is true.
    If 1/0=infinity, then 0×infinity=1. Likewise, 0×-infinity=-1. Your fraction always stayed the same, you arbitrarily switched it to negative by multiplying by -1.
    Think of it intuitively, if I asked you to divide a cake between 3 people, you'd cut 3 slices. For 2 people, cut it in half. For 1 person, don't cut it at all. For 0 people, cut the shit out of it infinitely many times until nobody can eat it.
    Likewise if you had to feed infinitely many people, your portions would approach 0 as the number of guests approached infinity.
    So yes 1/0=infinity, 1/infinity=0, and 0×infinity=1 😋😎🤥🤔
    Can you prove 0=infinity? If so, is the √(1) = 0×0 or infinity×infinity? 😂😂😂😂

    1/0=1,which means one is not divided so one is still one itself. 1/1=0.5 which means one is divided once.1/2=0.25 which means one is divided twice 1/3=0.125.....and so on and so on

  • jdcunnington

    The problem at 5:56 is that infinity is not just "a number". It's a concept. Kind of like an irrational number only going to the impossibly huge rather than the infinitesimally small (in additional decimal places). It's a number so impossibly huge that nothing can ever reach it. If we can never reach it, then at no point is 2/0 equal to 1/0 because it never ends. And negative never-ending is the same as never-ending. It's all infinite. Again, that's a concept, not a number.

    I know - there are probably a number of set theorists and math wonks here who will say I'm wrong. Fine. I'm just coming at it from the street level view, not the vaunted ivory tower view.
