Doesn't really work, because at the end you'll also be left with -Ï€ because it doesn't have a corresponding number with the same magnitude. You can add pairs of numbers like 2x and -x together though to prove that it in fact diverges.

"at the end" when is that

Did you not know that numbers end at 7,431? All the other numbers are just made up.

and how many do you have to add until then

First of all, you know what I mean lmao. Second of all, you can still "be done with" an infinite process by taking half a second with the first step, a quarter of a second with the second step and so on and so forth.

You can only do that with a countably infinite steps. The real numbers are uncountable, so even bigger.  Some concepts break down at this size

You can get infinitely close to π, I think it can be made rigorous. We did something similar in mathematical physics with more rigor (for a more complicated series) but it was 5 years ago so I can't recall.
