Description: Mapping for the vector subtraction operation. (Contributed by NM, 11-Sep-2007.) (Revised by Mario Carneiro, 23-Dec-2013.) (New usage is discouraged.)
Hypotheses
Ref Expression
nvmf.1  |-  X  =  ( BaseSet `  U )
nvmf.3  |-  M  =  ( -v `  U
)
Assertion
Ref Expression
nvmf  |-  ( U  e.  NrmCVec  ->  M : ( X  X.  X ) --> X )

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