Unit 2, Day 21

Agenda

1. Warm-up: Spot the Bug — units, not syntax
2. The Green Audit, day 3: the program — data from the file, arithmetic in a function, output for somebody who is not you
3. Test it against the hand-worked case, per Formulas as Algorithms
4. Judge it against the criteria on The Green Audit — Judging Your Own Work — and write down your weakest row. You get the first twenty minutes of next class to fix exactly that

Things to do before our next class

• Daily and yearly figures you believe, and can defend.
• Your weakest row named, in one sentence.
