(msg in 2 parts) Not too long ago, I edited math.stackexchange.com/questions/1351653/…, after discussing the problem with a friend of mine. It turned out that the difference between n_v being natural or 'just' an integer seems to be rather big.
This could lead to confusion, since the given example was in Z, not N. I edited something else that was completely irrelevant, just to get to enough changed characters. Nonetheless, the change was rejected. What should I do?
