    Well it was destined to be paradox, as the very first series 'A' is a paradox itself, as the sum of 1-1+1-1+1-1+1-1+...... Can be either 1 or 0 depending on the last quantity of the series, as it's till infinity it's unclear what is the last numeral, so the answer should be either 1 or 0, but, by solving this series i.e. by taking common we got 1/2, it's actually impossible, I think it's the average of 1 and 0, and we can't solve maths by taking a contradictory value and further assigning it, hence sum of all natural numbers was destined to be a paradox.

      is a Divergent series, so mistake starts from the point we assume the value of this series to be a constant just by doing addition substracting.
      By the way Mathematically applying the basic operations, even 1=2 can be proved and according to that any two given distinct numbers can be proved equal to each other but that's not true.
      1≠2, 2≠3, 3≠4,.....

    The key of infinity in math (Still not known rule) , like of BODMASS rule, is that nothing can be removed from infinity once it added to it, though can be rearranged and add more but can not remove, this is what is missing above and causes such paradox. Sometimes simplicity avoids big mistake. This is like a black hole , one is talking about taking back something from blackhole. So the statement that the sum of the infinite series 1+2+3+...infinity is equal to -1/12 this result is based on the assumption that division by zero is allowed. but division by zero is undefined, so the sum of the series is also undefined. There is a mathematical theorem that states that the sum of an infinite geometric series is equal to a / (1-r), where a is the first term of the series and r is the common ratio between the terms of the series. In the case of the series 1+2+3+...infinity, the first term is a=1 and the common ratio is r=1. So, the sum of the series would be:
    S = 1 / (1-1) = 1 / 0
    However, as I mentioned before, division by zero is undefined. So, the sum of the series is also undefined.

    Hello Mr. Aman,
    Captain XYZ( Indian armed forces) this side,
    I donot have a formal background of maths but I gave a thought on this series and found out following assumption flow in your calculations :
    You assumed 1+2+3+4........= S
    Now by assuming the series sum to be a finite variable S, you have forced the certainty on infinity(because only after that you were able to solve B =-4S +S =-3S but actually what you are solving is - -4* infinity + infinity).
    And due to this we see such an absurd answer!!

      You are right, when dignify infinity with the title of a number, you are inadvertently playing fast and loose with the concept of a number.
      For example in a normal number system if a+b = a+ c then b=c. But if you add infinity to the normal number set then
      Inf + b = Inf+c doe not allow us to infer that b= c.

    ramanujan is a legend mathematician but he was a human too. if someone will say 2+2=5 would you believe it? no but we have lots of proofs that supports it.

    Ramanujan was a great genius , but was certainly sure that this inequality is of course not correct . You can get it by incorrect treatment
    of diverging sums. There are similar results for conditionally convergent series ,for which Riemann proved that you can get any
    number as the sum , by choosing different orders of summation.

    What does Ramanujan’s infinity concept mean? Does it mean that our universe has an end point, or does infinity have an end also?

    this paradox happens because we dont know to use infinity yet..we cant subtract infinity to infinity, it wont give you zero or any positive or negative number..here in this equation this paradox happened because it took infinity substracted from infinity as ZERO which is actually not zero..but Ramanujam used this paradox to solve some divergent series..the paradox is neither true or false but just what its defined, and used for infinite series to solve equations

    7:32 the first step is itself wrong because if a series is going upto infinity then how can you take something equal to infinity when it's value is not defined
    Also if u are just naming the series with A how did u take the series EQUAL to A.
    Similar case with S and B series as well. Hope you understand

    Ramanujan's story is mind blowing. Eyes tear when I hear about his magical mind of maths...😍
