Talk:Non-Zero Real Numbers under Multiplication form Abelian Group

Am I missing something or does this follow from: Real Numbers under Multiplication form Monoid, Inverses for Real Multiplication and Invertible Elements of Monoid form Subgroup of Cancellable Elements. Wanfactory (talk) 17:39, 20 December 2016 (EST)


 * Removing a proof and replacing it with something else is considered suboptimal. See Help:FAQ/Questions about contributions/You undid my corrections. --prime mover (talk) 17:50, 20 December 2016 (EST)


 * The previous proof was considered questionable. The invertible elements of Monoid result seem to take care of the problematic parts. Wanfactory (talk) 18:13, 20 December 2016 (EST)
