Why is sum of: 1+2+3+4+...∞ = -1/12 ?

[moma]

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.

[QIII]

Who is saying that?

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.
