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