Natural Numbers

  • Definition: Natural numbers are the counting numbers, starting from 1 and extending infinitely. They are used for counting objects.
  • Examples: 1, 2, 3, 4, 5, 6...
  • Symbol: N

Whole Numbers

  • Definition: Whole numbers include all natural numbers and zero.
  • Examples: 0, 1, 2, 3, 4, 5, 6...
  • Symbol: W

Integers

  • Definition: Integers encompass all whole numbers and their negative counterparts.
  • Examples: ... -3, -2, -1, 0, 1, 2, 3...
  • Symbol: Z

Key Differences

Number Type Description Examples
Natural Counting numbers starting from 1 1, 2, 3, 4, 5, 6...
Whole Natural numbers including zero 0, 1, 2, 3, 4, 5, 6...
Integer Whole numbers and their negative counterparts ... -3, -2, -1, 0, 1, 2, 3...

In essence:

  • Natural numbers are a subset of whole numbers.
