Natural Numbers:
Natural numbers are the counting numbers that start from 1 and go on infinitely without any end. These are the numbers that we use in our everyday life for counting and measuring. Natural numbers can be represented as N = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, ...}

Whole Numbers:
Whole numbers are the numbers that include all the natural numbers along with zero. These numbers are represented by W = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, ...}. Whole numbers are used for counting objects that include zero, for example, counting the number of chairs in a room, the number of students in a classroom, etc.

Difference between Natural and Whole Numbers:
The main difference between natural and whole numbers is that natural numbers start from 1, while whole numbers include zero. Natural numbers are used for counting and measuring objects that cannot be divided, while whole numbers are used for counting objects that include zero.

Examples:
- The set of natural numbers is N = {1, 2, 3, 4, 5, ...}
- The set of whole numbers is W = {0, 1, 2, 3, 4, 5, ...}
- If you are counting the number of apples in a basket, you would use natural numbers, starting from 1. If the basket is empty, you would use the whole number zero.
- If you are counting the number of students in a classroom, you would use whole numbers, starting from zero, as there could be no students in the classroom.

Summary:
- Natural numbers are the counting numbers that start from 1 and go on infinitely without any end.
- Whole numbers include all the natural numbers along with zero.
- Natural numbers are used for counting and measuring objects that cannot be divided, while whole numbers are used for counting objects that include zero.
