CLASSIFICATION OF NUMBERS

  • Natural Numbers: Counting numbers (1, 2, 3...).
  • Whole Numbers: Natural numbers + zero (0, 1, 2, 3...).
  • Integers: Whole numbers + negative numbers (...-2, -1, 0, 1, 2...).
  • Rational Numbers: Numbers that can be written as fractions, decimals, or percentages (including all the above).
The video explains how each group expands to include the previous one and gives examples to help classify different numbers.
