13 lessons

One lesson for each chapter, from sets through math and art. Read it, then open the same chapter in the book.

  1. 1SetsA set is a collection whose membership you can decide.
  2. 2LogicA statement is a sentence that is true or false, and a conditional fails in only one case.
  3. 3Number theoryPrimes, factors, and the two number systems you will keep meeting.
  4. 4Number representationA number and the marks used to write it are different things.
  5. 5AlgebraThis chapter is the algebra the rest of the book actually uses.
  6. 6Money managementSimple interest stays on the original principal. Compound interest pays interest on interest.
  7. 7ProbabilityA probability is a number from 0 to 1. The complement is whatever is left.
  8. 8Describing dataAn outlier pulls the mean and barely moves the median.
  9. 9Metric measurementInside one kind of measure, the metric system moves by powers of ten.
  10. 10GeometryAngles in a triangle add to 180°, and a right triangle obeys a² + b² = c².
  11. 11Voting and apportionmentThe same ballots can name different winners under different rules.
  12. 12Graph theoryThe degrees of a graph add up to twice the number of edges.
  13. 13Math and artThe Fibonacci sequence adds the two previous terms, and a tessellation covers the plane with no gaps.
