Classification of Numbers
- Whole numbers include all natural numbers plus zero; examples are 0, 1, 2, and 3.
- Natural numbers are the counting numbers beginning from 1; the set is {1, 2, 3, 4, ...}.
- Integers consist of whole numbers and their negatives, including zero; examples are -3, -2, -1, 0, 1, 2, 3.
- Rational numbers can be expressed as fractions and include terminating decimals; examples are 1.89 and 0.34.
- An integer can be positive or negative; examples include 12, -15, and -100.
- A definition of rational numbers includes those that can be written as a fraction, such as -5½ and 1 ⁷/₉.
- Irrational numbers cannot be expressed as fractions and include non-terminating, non-repeating decimals; examples are √2 and π.
- Irrational numbers also arise from non-perfect square roots, characterized by decimal values that do not repeat or terminate.
- Terminating decimals are classified as rational as they can be accurately expressed as fractions.
- Examples of irrational numbers include √5 and √114.
- Key characteristics of natural and whole numbers exclude fractions and decimals; they represent positive quantities only.
- Rational number examples illustrate both decimal forms and mixed numbers, demonstrating versatility in representation.
