invert_real(Abs(x) - n)[2](1 week) - not_empty_in ({n} .intersection(-oo, 0))
[2](1 week)
Brief: return invert with the information of the set in which the invert is valid:
for e.g.
invert: Abs(x) - n should return (-n).intersection(-oo, 0) U (n).intersection(0, oo)
and not just {-n, n}, so that the above would return EmptySet() when n is negative.
