# Thread: isomorphic rings

1. ## isomorphic rings

1. How do I prove that two isomorphic finite rings have the same number of opposite elements?

2. And if two finite rings have the same number of elements and opposite elements does it mean that they are isomorphic?

What do you mean by "opposite elements"? Additive inverses? Do you know what "isomorphic" means?
