      Finally, someone who noticed. To me, in the first place, it doesn't even make sense to consider the two possibilities of "Odd" and "Even" as they cannot describe an infinite summation. Only a finite countable number can be odd or even, not infinity. That is my opinion, maybe I just missed or misunderstood something.

    There's a big problem to start with: We cannot talk about the end of an infinite series, i.e. if the total number of items in a series is even or odd, since **infinity by definition has no end**.
    Actually, it has not even a start. So starting with 1 or whatever else has no meaning either.

    This makes no sense for some reasons. First, you keep increasing so how can the result be lower? If you add 1 to infinity (infinity + 1) it will simply expand not shrink. Secondly, why is a subtraction used on something that keeps increasing? You could simply use the odd numbers for the odd series (2 + 4 + 6 + etc).

    I have no problem with the -1/12, but the equal sign requires the notion of a regularized sum. Stating that such sums are equal to a value, is only true given a method to assign a value, like Ramanujan Summation, or running average, or …. But that is not a “normal” summation.
    I also believe that what you are showing is NOT Ramanujan Summation.
    All of this is done quite well and complete by Mathologer, which I would recommend to view.

      it's not mathematically incorrect, because:
      S1= 1-1+1-1+1-1 any number of times will be 0
      and
      S2=1-1+1-1+1-1 any number of times will also be 0.
      so you're trying to say that 0≠0?
      I think that 0=0 is an obvious fact
      S1 and S2 are nothing but 0's being added infinite number of times
      if the number being added is just 0, it doesn't make any difference as to how many times you add it, the result will be 0 only.
      from all dimensions and reasons, I believe that the assumption S1=S2 is mathematically correct.

Moreover in s4 why did we shift the no.s to 1 place right for substracting them from s3? If we'd not followed this the outcome would'n different? There are more questions but wanted to start with the basic first. Thanks.

Likewise S3 is not equal to 1+2+3..... etc. There is simply no such number. Rather, it was a joke by Ramanujan

    So many mathematical mumbo-jumbo, hocus-pocus steps here but conveniently violated the basic mathematical axiom of Addition Property of Equality (and by extension, Multiplication Property of Equality and all other mathematical properties of equalities). 1. The APE's use is limited to finite NUMBERS. Once you include infinity in the equation, you cannot use APE, otherwise you will get weird results, like this Ramanujan Summation. 2. Infinity is a CONCEPT, it is not a number. Hence it cannot be subjected to mathematical operations. How 'mathematicians' failed to see these is beyond me (I'm not a mathematician).

    This is as foolish as proving 1=0 when you apply the wrong operations such as dividing by zero. Here, S1 and S2 serieses are the root of all evils. Infinity does not end in even or odd number of terms. That wrong assumption makes this absurdity possible. Just because something has the name of Ramanujan doesn't become true by default.

    If you denote the continuous sequence of additions and subtraction as S, then S will stand for an endless or undefinable series of such arithmetic operations, but not a single and well-defined quantity. Hence, the result of the arithmetic operation as a single and well-defined quantity, after such nonsensical manipulations of human -invented defective notions of mathematics, and the endless series S are obviously 2 different values.
    An endless series of arithmetic operations, no matter whatever sort of arthrimatic operation it is, it will never ever stop to give any result
    So, An endless series of numbers and a number are two complete different mathematical notions. One is undefinable and the other is definable
    Therefore, once you have claimed that they are equal, you have also unconsciously claimed that you have been out of your mind. No need of any proof here
    If s = 1 + 2 + 3 + 4 +... Going to infinity
    4s = 4 + 8 + ... going to infinity
    could be possible, then it would be the same as claiming that that S = 4S, 1 = 4, 2= 8 , 3 =16, 4 =32 ... because the length from the starting point of the 2 endless series to infinity is the same or constant, and thus the number of additions of the first endless series and the number of additions of the 2nd endless series have to be the same for the length of the first endless series and that of the 2nd series to be the same because both of the endless series of additions start from the same starting point and stop at infinity, which is the same ending point
    Here are a 1-D visualisation of the 2 endless series of additions, which show that their lengths of addition operations have to be equal, while their numbers can be different
    C = 1--------------------------------------------infinity
    4C= 4--------------------------------------------infinity
    It is obviously nonsense
    What's wrong with such nonsensical manipulation here is that the guy took advantage of the ambiguity of the notion of going to infinity, which is obviously an unknowable unknown or undefined value, to insert this baseless claim. But the 2:series of additions have to have the same number of additions because they both begin from the same starting point and ends at the same ending point. The ending point here is infinity, and there can be only one infinity, but not 2 infinites. Hence,the number of additions of the 1st endless series of additions and the number of additions of the 2nd endless series of additions have to be the same. Both of the resultant outcomes of the 2 endless series of additions have to be infinity, having to stop at infinity, because infinity is the largest possible value, although they have different terms in the same number of additions. So, his mathemstical statement is the same as claiming that 1=4, 2 =8, 3=16, 4 =32 because that is the only one way for the 2 endless series of the same number of additions to end up with the same final output, which has to be infinity, but that only one way is obviously totally absolutely absurd
    Ignorant human mathematicians have the same problem of misunderstanding of the actual roles of human-invented numbers, and considering the unknowable unknown or undefinable value "infinity" as a specific value in their nonsensical mathematical claims
