Theorem subm0cl 13691
Description: Submonoids contain zero. (Contributed by Mario Carneiro, 7-Mar-2015.)
Hypothesis
Ref Expression
subm0cl.z  |-  .0.  =  ( 0g `  M )
Assertion
Ref Expression
subm0cl  |-  ( S  e.  (SubMnd `  M
)  ->  .0.  e.  S )

Proof of Theorem subm0cl
Dummy variables  x  y are mutually distinct and distinct from all other variables.
