# Interactive video lesson plan for: RNT2.2. Principal Ideal Domains

#### Activity overview:

Ring Theory: We define PIDs and UFDs and describe their relationship. Prime and irreducible elements are defined, and conditions for implication are given.

(second version: corrections to definition of prime and irreducible; comment should be 'R UFD implies R[x] UFD, improved proof that, in UFD, irreducible implies prime).
