  1. Aim #1.2: How are real numbers classified?

  2. Problem 1: Classifying a Variable • You classify a variable or a number by naming the subset of the real number that gives you the most information.

  3. Now you try: • In problem 1, if each participant made a donation of $15.50 to a local charity, which subset of real numbers best describes the amount of money raised in dollars?

  4. Problem 2: Graphing Numbers on the Number line

  5. Problem 3: Comparing Real Numbers

  6. What are the number properties? • The opposite or additiveinverse of any number a is –a. • The reciprocal or multiplicative inverse of any nonzero number a is 1/a.

  7. Properties of Real Numbers

  8. Problem 4: Identifying Number Properties

  9. Now you try: • Which property does the equation illustrate? • 3(g + h) + 2 g = (3g + 3h) + 2g

  10. Now you try: • How do and 6.25 compare? Use < or >. • Let a, b, and c be real numbers such that a<b and b< c. • How do a and c compare?

  11. Summary:Answer in complete sentences. • How are real numbers classified? • What is another name for a reciprocal? • How is the additive identity property similar to the multiplicative identity property? How is it different? • Give an example of a number that is not rational. Explain why it is not rational.
