Irrational numbers are defined as numbers that are not rational. Focus of Topic B is writing decimal expansions of numbers. Students learn why the long division algorithm leads to the decimal expansion of a number. Students learn how to determine the decimal expansion of irrational numbers, including pi. Topic B: Decimal Expansion of Numbers
