Hello.

Im having trouble getting started on this problem and am having trouble with rings in general. The problem is

Find all units, zero-divisors, idempotents, and nilpotent elements in Z_3 (+) Z_6. (+) is the external direct product.

The chapter is very vague and doesn't even talk about idempotents and nilpotent. If someone could give me some type of explanation to help get me started would be great. Thanks!
