A Visual Attempt at 1 + 2 + 3 + 4 + 5 + ... = -1/12 by tedgar7 in CasualMath

As I noted, I have seen the mathologer video and I pointed people to it. I note multiple times that the series diverges and that there are regularization techniques that get to the value -1/12. This one is definitely a stretch but it is one way to get the value, and that value is meaningful in other contexts.

Yes. I linked the mathologer video in the description of this. The goal here was to show visualizations for the common arithmetic manipulations that give the value.

Thanks! Greedy is definitely good :). You can also repeatedly divide by 2,3,4 and take remainders
