Assertion

Ref	Expression
addass	|- ( ( A e. CC /\ B e. CC /\ C e. CC ) -> ( ( A + B ) + C ) = ( A + ( B + C ) ) )

Proof of Theorem addass

1		ax-addass 8287	1 |- ( ( A e. CC /\ B e. CC /\ C e. CC ) -> ( ( A + B ) + C ) = ( A + ( B + C ) ) )

This proof depends on syntax axioms:   -> wi 4   /\ w3a 1009   = wceq 1402   e. wcel 2209  (class class class)co 6088   CCcc 8183   + caddc 8188

This proof depends on axioms:  ax-addass 8287
