Description: Locatedness of addition on positive reals. Lemma 11.16 in [BauerTaylor], p. 53. The proof in BauerTaylor relies on signed rationals, so we replace it with another proof which applies prarloc 7311 to both and , and uses nqtri3or 7204 rather than prloc 7299 to decide whether is too big to be in the lower cut of (and deduce that if it is, then must be in the upper cut). What the two proofs have in common is that they take the difference between and to determine how tight a range they need around the real numbers. (Contributed by Jim Kingdon, 5-Dec-2019.) |
