    lol 1-1, 2-2 etc.

    How do you get 1 + 2-1?

    You need to distribute that minus sign to all numbers in the sequence. You can’t leave off the first one.

      It’s an infinite series, love, I just moved it, there are still enough elements in them because, well, they are infinite. If you are so sad about it, write the second one as 0-S, changes nothing but now you have a donut to pair up with the 1 in the first series.

      He has a plus one, and a minus one, a plus two, and a minus two, and so on. This is analogous to how conditionally convergent series can be modified to give any finite (or infinite) sum merely by changing the order of the terms.
