%proving positive_if_real_pos

With these allowed/disallowed theorem/theory presumptions (e.g., to avoid circular dependencies), we begin our proof of
positive_if_real_pos:
(see dependencies)

positive_if_real_pos may now be readily provable (assuming required theorems are usable).  Simply execute "%qed".
