In this video, we discuss how to prove a disjunctive statement, aka an or-statement. Using this technique, we prove Euclid's lemma about divisibility by primes. 

This is lecture 21 (part 1/3) of the lecture series offered by Dr. Andrew Misseldine for the course Math 3120 - Transition to Advanced Mathematics at Southern Utah University.
