    I would define the answer of A/0 = +/- infinity... does it make sense? Just like when we are using the quadratic equation, we are expecting both + and - answers...

    This is how we can prove
    1/0 =infinity , similarly
    =》 1/infinity = 0
    Infinity can be any number
    So let we take
    Infinity=10000............
    So 1/10000......... = 0.000000..........1 approximate 0

    Isn't the 2/0 a different infinity. Since all infinities aren't equal?

    What is Negative Infinity and Positive Infinity are the same thing. Just one infinity.
    We know the Earth is round, but our Maps are flat because it is merely a projection of what is really there.
    We know the Cartesian plane we see could be thought of as a projection of a 4-dimensional complex plane (since each axis is 2-dimensional, having both a real and imaginary part) when the imaginary parts of both axes are zero.
    What if the Cartesian Plane we draw is also actually a projection of a sphere, (or some other shape that follows weird rules of higher dimensional geometry,) and when travelling towards infinity, you always find yourself returning from negative infinity back to where you started.
    The value of anything divided by zero will be the value infinity. Not positive infinity, not negative infinity. Just, infinity.

      @Illuso Senpai so multiplication is NOT repeated adding. I think the concept of multiplication is repeated adding cannot be applied in such situation. That makes confusion for students.

    But when you divide 1 by 1, then 0.1, then 0.01, then 0.001 etc. you're only approaching to 0, but you're never gonna get, it's always gonna be 0.0...1 so is it right to assume that 1/0=∞?

      Yeah, You need to know if the x is close to negatives or positives numbers. If its close to negatives , the answer will be minus infinate and if its close to positives the answer will be plus infite. So the limit x->0 doesnt exist. By close to pos or negs I mean that the f(x) is >0 or its

    Another problem: if 1/0 = infinity and 1/0 = negative infinity, then 1/0 = infinity = negative infinity. And the only way that a negative is equal to a positive, is if that number is 0. Then, infinity=0.

    Jeremy Lenon 16 days ago

    I believe this whole argument is falsely constructed. The idea that division is repeated subtraction is the only definition. That is division's purpose. Therefore, the only solution to this is infinity. You cannot define division using division, just like you cannot define a word by using that word in the definition.

  • Дмитрий Хабаров

    i don't get your logic. You take 1 marker in the right hand and 2 markers in the left hand and say - they don't equal. BUT! You take 1, divide it by 0.1 and say it equals 10... How can you divide something and have it equal a grater number? And i mean physically. Can i divide an apple and get 10, 100, 1000 apples?.. I did try but for some mysterious reason it's not working. Besides, you try to make markers represent 2 infinities. How does that work? They do equal, because they are infinite. It's not like one infinity starts with a 1 and the other starts with a 2. No. They are equal because they're both infinities. So, the answer to the problem 1/0 is actually very simple - it's 1. Zero is nothingness. When you divide anything by nothing you don't get nothing, you get the original thing. At least that's what the apple experiment let me to believe. Because you're actually not dividing at all.
    So question is why dividing 1 apple by 0.1 = 10 apples? Actually it equals to 10 pieces of that 1 apple. The apple is still there. So when you divide it by 0 - you are not dividing it at all. It does not disappear. So, it cannot equal 0. It has to be equal to 1...

      @Alberto Romanhol it actually tends to negative infinity and infinity. If you apply lateral limits, you see that if you approach 0 from the left, it tends to negative infinity, if you aproach from the right you get it tends to infinity. So theres no limit to 1/x

  • Anderson Klein
    Anderson Klein 18 days ago

    While in a class in high school or calculus 1 or something, the teacher pointed out what was probably in everyone's mind: Some people conjecture that this could just proof that minus infinity and infinity are connected and the number wheel connects there. Watching this it just hit me... What if there is a plane of numbers, like the imaginary numbers, which exist parallel to real numbers and there is a whole field of mathematics to be found?
    Maybe it could also one day be useful in explaining things about the universe that would make no sense otherwise...

      We subtracted .1 from 1 10 times. Therefore, 1/0.1 equals 10.
      The corresponding process would follow for 1/0.01.

  • Isaac Joseph
    Isaac Joseph 19 days ago

    what if you did 0/0 wouldn't it always equal zero so now you don't end up with infinity. and i'm guessing you approaching this like everyone else but you never talked about what infinity means. infinity is like a problem that never ends but you were saying that 1/0=infinity and 2/0=infinity and just because they ended with infinity your saying that must mean their the same answer when really they don't. these two numbers never will get the same amount nor will they ever equal each other and so saying one number of infinity = another number of infinity is 100% wrong. i guess theirs something i'm missing or my education hasn't gotten to the level of what mathematicians perceive infinity to be so if i'm wrong on any of this let me know

      The inner expression needs to be evaluable before the Commutative Property can be applied.

    Explanation is just all wrong... He says 2/0 = infinite = 1/0 and then he says we have to assume 1 = 2 but all we so is assume infinity = infinity because 2/0 =/= 2 and 1/0 =/= 1 and noone said anything like that... You're basically saying... 2/2 = 1/1 so 2 = 1... No just wrong did a false explanation

    The real answer is in the what we think the problem is. Positive and negative are just directional so positive infinity does in fact equal negative infinity. Also mathematicians stumbled upon a truth they can't understand, 1 can equal 2 in that we are all one consciousness.
