Content
Definition of Whole Numbers:
Whole numbers are the set of numbers that include all the natural numbers (0, 1, 2, 3,…) without any fractions or decimals. They are used in counting and ordering.
Properties of Whole Numbers:
- Closure Property: The sum or product of any two whole numbers is also a whole number. For example, 2 + 3 = 5 and 4 × 2 = 8.
- Commutative Property: The order in which two numbers are added or multiplied does not change the result. For example, 4 + 2 = 2 + 4 and 3 × 5 = 5 × 3.
- Associative Property: When adding or multiplying three or more whole numbers, the way in which they are grouped does not affect the result. For example, (1 + 2) + 3 = 1 + (2 + 3).
