Theorem archsr 8097

Description: For any signed real, there is an integer that is greater than it. This is also known as the "archimedean property". The expression [⟨(⟨{𝑙 ∣ 𝑙 <_Q [⟨𝑥, 1_o⟩] ~_Q }, {𝑢 ∣ [⟨𝑥, 1_o⟩] ~_Q <_Q 𝑢}⟩ +_P 1_P), 1_P⟩] ~_R is the embedding of the positive integer 𝑥 into the signed reals.
