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