U2L3: Making Decisions Learning Goals Page 3

- What is the primary difference between the first two examples of ways to define ≥ (shown below)? The goal of this discussion is for students to see that a good optimization is that you never need to program if some predicate report (true) else report (false), you can just do report (some predicate).
