Description: Equivalence for positive signed real. (Contributed by NM, 17-May-1996.) (Revised by Mario Carneiro, 15-Jun-2013.) (New usage is discouraged.)
Hypothesis
Ref Expression
map2psrpr.2 𝐶R
Assertion
Ref Expression
map2psrpr ((𝐶 +R -1R) <R 𝐴 ↔ ∃𝑥P (𝐶 +R [⟨𝑥, 1P⟩] ~R ) = 𝐴)
Distinct variable groups:   𝑥,𝐴   𝑥,𝐶

Proof of Theorem map2psrpr
Dummy variables 𝑦 𝑧 are mutually distinct and distinct from all other variables.
