A companion textbook
Functions, slope, and linear modeling — plus the Excel moves (formulas, cell references, basic graphs) you'll lean on the rest of the term.
Read chapter →Percent, unit conversions, and building a budget you could actually use — anchored by the first Major Assignment.
Read chapter →Simple vs. compound interest, the CPI and inflation, and annuity formulas for planning how money grows over time.
Read chapter →Short- and long-term loans — auto loans, credit cards, student loans, and mortgages — plus an APA-style written analysis. The heaviest week of the course.
Read chapter →Descriptive and inferential statistics — mean, median, mode, spread, the normal distribution, and the margin of error behind every poll headline.
Read chapter →Counting, permutations and combinations, theoretical and experimental probability, and expected value. The math of uncertainty — and the engine behind every insurance premium, lottery ticket, and game of chance.
Read chapter →Income taxes, stocks, and bonds — the last chapter of the book, and the most practical: reading a paycheck, understanding the progressive bracket system, evaluating stocks and bonds, and choosing a diversified portfolio.
