  2. Date 09/14/09 Sec 1-3 Exploring Real Numbers

  3. Goal: • To classify numbers • To compare numbers

  4. ... And Why To determine which set of numbers are appropriate for real-world situations, as in Example 2.

  5. Key Words: Natural #’s: 1, 2, 3, 4, 5, … Whole #’s: 0, 1, 2, 3, 4, … Integers: …-2, -1, 0, 1, 2, … Rational #: Any # that can be written in fraction form, in decimal form they are either terminating, 6.27, or repeating, 8.222…

  6. Key Words: Irrational #: Any number that can not be written in fraction form. Example: Inequality:

  7. Key Words: Opposite: Two #s that are the same distance from 0 on a # line but lie in the opposite direction. Example: Absolute Value: The distance that a # is from 0 on a # line. Example:
