    Study Notes

    Classification of Real Numbers

    • Natural Numbers: Positive integers starting from 1, including examples like 3, √25 (5), √100 (10), and 85. No negative or fractional numbers.

    • Whole Numbers: Include all natural numbers and zero. The only example provided is 0.

    • Integers: Consist of whole numbers, both positive and negative. Examples include -4, -73, and -87.

    • Rational Numbers: Numbers that can be expressed as a fraction or ratio of integers. Examples range from simple fractions like 1/4, 3/2, and -2/5 to decimals such as 5.67, -0.987987 (repeating), and -5.4.

      • Repeating decimals like 4.313131 can also be categorized as rational.
    • Irrational Numbers: Cannot be expressed as a simple fraction. They have non-repeating, non-terminating decimal expansions, with examples including 3.14159... (π), √10, √5, and 0.43892...

    • Key Characteristics:

      • Natural numbers are always whole and positive.
      • Whole numbers include zero.
      • Integers expand to include negative numbers.
      • Rational numbers can be decimals that are terminating or repeating.
      • Irrational numbers always result in non-repeating and non-terminating decimals.
    • Examples of Classification:

      • √25 is classified as natural (value 5).
      • -0.474747 (repeating) fits within rational classification.
      • 3.14159... is categorized as irrational due to its decimal nature.
    • Usage: Understanding the classification aids in identifying, comparing, and performing operations on different types of numbers.
