What is smaller than every positive x
is smaller than the interval (0, oo).
That which is not.in the interval (0,∞)
is not an end of (0,∞).

No point in the positive axis is

No countable.to number is largest countable.to.
No rat. > 0 with countable.to num. and den.
is largest rat. > 0 with countable.to num. and den.
or smallest rat. > 0 with countable.to num. and den.
∀p/q ∈ ℚ⁺: ℚ⁺ ∋ p/(q+1) < p/q < (p+1)/q ∈ ℚ⁺
No (0,∞).split F,H has a situating.point x
(x last.in.F or x first.in.H) such that
x is first in F∪H = (0,∞) or
x is last in F∪H = (0,∞)
No rational > 0 with countable.to num. and den.
and no situating point of any (0,∞).split
is an end of (0,∞)
There are no other points in (0,∞)
