Theorem rngoaddneg1 39128

Description: Obsolete theorem, use ringgrp 20515 and grplinv 19250 instead. Adding the negative in a ring gives zero. (Contributed by Jeff Madsen, 10-Jun-2010.) (New usage is discouraged.) (Proof modification is discouraged.)

**Hypotheses**
Ref	Expression
ringnegcl.1	⊢ 𝐺 = (1^st ‘𝑅)
ringnegcl.2	⊢ 𝑋 = ran 𝐺
ringnegcl.3	⊢ 𝑁 = (inv‘𝐺)
ringaddneg.4	⊢ 𝑍 = (GId‘𝐺)

**Assertion**
Ref	Expression
rngoaddneg1	⊢ ((𝑅 ∈ RingOps ∧ 𝐴 ∈ 𝑋) → (𝐴𝐺(𝑁‘𝐴)) = 𝑍)
