Description: A group multiple of the identity, for nonnegative multiple. (Contributed by Mario Carneiro, 13-Dec-2014.)

Hypotheses

Ref	Expression
mulgnn0z.b	|- B = ( Base ` G )
mulgnn0z.t	|- .x. = (.g ` G )
mulgnn0z.o	|- .0. = ( 0g ` G )

Assertion

Ref	Expression
mulgnn0z	|- ( ( G e. Mnd /\ N e. NN0 ) -> ( N .x. .0. ) = .0. )

Proof of Theorem mulgnn0z

Dummy variables x y are mutually distinct and distinct from all other variables.
