Assertion

Ref	Expression
addrid	|- ( A e. CC -> ( A + 0 ) = A )

Proof of Theorem addrid

Step	Hyp	Ref	Expression
1		ax-0id 8288	1 |- ( A e. CC -> ( A + 0 ) = A )

This proof depends on syntax axioms:   -> wi 4   = wceq 1402   e. wcel 2209  (class class class)co 6085   CCcc 8178   0cc0 8180   + caddc 8183

This proof depends on axioms:  ax-0id 8288
