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