If R and F are rings, then RxF is a ring. In particular, if R is a finite non-commutative ring and F is a field...

so then??...
 
then RxF is an infinite non-commutative ring...
so...

Do you mean that RxF is a counter-example ? but RxF has infinite non-unit elements .
 
Silly me! I should read the question.
