Clearly define the relationship between Natural Numbers, Whole Numbers, and Integers. Natural numbers are the counting numbers (starting at 1). Whole numbers include all natural numbers plus zero (0). Integers encompass all whole numbers plus the negative counting numbers (..., -2, -1). Learn how to identify and correctly denote each set, and crucially, understand that integers do not include decimals or unsimplified fractions like -22/7. This video uses a Venn Diagram to visually illustrate how these number sets are nested within one another, reinforcing fundamental concepts for Grade 8 and higher mathematics.
