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