Jun 30, 2016 at 9:24	comment	added	Denker		@KevinCruijssen like you said `-123` becomes `"-+1+2+3"` after joining which yields the correct result when you `eval` it. Try `eval("-+1")` for example which results in `-1`.
Jun 30, 2016 at 9:19	comment	added	Kevin Cruijssen		I never used Python, so forget my possible ignorance, but how does the `eval` and `join` know to take the negative first digit for negative input? I would expect `-123` to become something like `- + 1 + 2 + 3` written out, but apparently it isn't.. (Or is it, and it automatically merged `- + 1` to `-1` as second step?)
