Chapter One additional terms

Two terms that were not in Chapter One, but should be (and that you will be expected to know for the exam):
1. Loss - you don't always get a profit when you subtract expenses from revenue
2. Arbitrage - the discrepancy that exists, and the ability to capitalize upon it, between market prices. I can buy generators cheap in Michigan and sell them here for much more the day after an ice storm knocks out everyone's electricity.
