## Main Question or Discussion Point

I watched a video where apparently the sum of all natural numbers = -1/12. The video starts by saying

S = 1-1+1-1+1-1+1-1... to infinity. He then says this sum does not have an answer, it's constantly between 1 and 0 depending on where you stop it. So he just takes the average and says 1/2. How is this legit mathematics?

6/0 does not have an answer so we can't just make one up and say oh let's just say it's 94 or something. The thing is it does actually = -1/12 but only if you assume the first part actually does = 1/2, which it doesn't, cos it doesn't have an answer -_-
