%proving real_neg_within_real
With these allowed/disallowed theorem/theory presumptions (e.g., to avoid circular dependencies), we begin our proof of real_neg_within_real: (see dependencies)
real_neg_within_real may now be readily provable (assuming required theorems are usable). Simply execute "%qed".
