MAT-144 · Mathematical Reasoning Topic 07 · Taxes & Stocks
Topic 07 · Welcome

Welcome to Taxes & Stocks.

This is the last content week of the course, and the most practical: taxes and the stock market. By the end of the week you'll be able to read your own pay stub, compute the tax owed on a hypothetical income across the U.S. progressive brackets, read a stock quote and a bond quote, and understand why a real-world investment portfolio mixes stocks and bonds rather than concentrating in one.

Topic 7 has no per-topic review — the cumulative Final Exam Review (ALEKS, 38 questions across Topics 1–7) replaces it. The 2 Discussion Questions are the only graded items besides the Final Exam itself. Lessons 1–3 cover income taxes; Lessons 4–6 cover stocks and bonds; Lesson 6 ties both halves together as the course finale.

Start Lesson 01 Topic overview

By the end of this week, you'll be able to:

  • Analyze systems of stocks and bonds to help develop financial literacy skills.
  • Analyze the system of income taxes to help develop financial literacy skills.

Four phases, in order. Don't skip ahead — each one sets up the next.
