| May 24, 2023 at 19:03 | comment | added | Timo Reichert | For my purposes we can assume that 0 counts as a positive element, but not as a negative element. Sorry, I will edit that out. | |
| May 24, 2023 at 18:34 | comment | added | LSpice | You say that $0$ counts as a positive element. Does it also count as a negative one? \\ Also, I think that this probably is not a nt.number-theory question. | |
