    Post Why is sum of: 1+2+3+4+...∞ = -1/12 ?

    Hello,
    Why people are saying that sum of positive integers up to ∞ is: -1/12

    So: 1 + 2 + 3 + 4 + 5 + ... ∞ = -1/12

    Tell me.

    It isn't, but lots of people have erroneously said it.

    I pretty much suck at any math which requires me to count higher than the number of fingers on my hands.

    i once tried to count to 1023 using my fingers. my friend suggested also using my toes so i could go all the way to 1048575 but i rejected that idea. i quit somewhere around 64.
