How do you prove a mathematical claim? This video provides a step-by-step process to help you prove simple, direct proofs. We begin with the assumption, apply the definition, do some manipulations, apply the definition of the conclusion, and finish at the conclusion.

We will investigate the claim "the sum of two even integers is even" as a template for this proof style.

Learning Objectives:
1) The four major steps in proving a theorem
2) The give details that occur in the body of a proof
3) The rational behind the various steps in our first formal proof.
