Description: The subring module inherits a zero from its ring. (Contributed by Stefan O'Rear, 27-Dec-2014.)
Hypotheses

sralmod0.a  |-  ( ph  ->  A  =  ( (subringAlg  `  W ) `  S
) )
sralmod0.z  |-  ( ph  ->  .0.  =  ( 0g
`  W ) )
sralmod0.s  |-  ( ph  ->  S  C_  ( Base `  W ) )
sralmod0g.w  |-  ( ph  ->  W  e.  X )
Assertion
Ref Expression
sralmod0g  |-  ( ph  ->  .0.  =  ( 0g
`  A ) )

Proof of Theorem sralmod0g
Dummy variables  a  b are mutually distinct and distinct from all other variables.
