I would like to begin 2019 with a bit of review. I hope this review will accomplish a few things: 1. Establish some important mathematics facts 2. Establish context in which to view these mathematics facts 3. Establish the REAL purpose of the previously presented example 4. Establish a revised general approach for teaching mathematics

EXAMPLE: Discuss the system of inequalities Begin by observing that this is a system of three linear inequalities in two variables. The solution set for each individual inequality is a half-plane. (The Law of Trichotomy). The solution set for the system is the set of points which are solutions of 2x + 5y ≥ 10
