Chapter A
Financial fundamentals
What it covers
Money as a unit of account, the difference between a price and a promise, and the ordinary distinction between spending, saving, and investing as definitions rather than tips.
What you can learn
How beginner textbooks name cash, interest as a concept, and inflation as a change in purchasing power — without telling you what to do with a surplus.
Method
Start with the word, then the document that uses it. Avoid slogans. Keep the limit of the definition in the same paragraph.
Typical educational use
A first pass before reading a public report or a news table, so the nouns are already mapped.
Concepts
Unit of account, purchasing power, nominal versus real language, time as a dimension of a claim — not as a forecast.
