Whole numbers are a set of numbers that include all the counting numbers (1, 2, 3, …) and zero (0). Whole numbers are positive integers and zero; they do not include any negative numbers or fractions.

Here are some key points to understand about whole numbers:

1. Whole numbers are used to count objects or quantities that are complete and do not have any fractional or decimal parts. For example, the number of students in a class, the number of apples in a basket, or the number of days in a week can be represented using whole numbers.

2. Whole numbers start from zero and go indefinitely in the positive direction. You can keep counting whole numbers by adding 1 to the previous number. For example, 1, 2, 3, 4, 5, and so on.

3. Whole numbers are closed under addition and multiplication, which means that when you add or multiply two whole numbers, the result will also be a whole number. For example: 3 + 4 = 7 and 2 x 5 = 10.

4. Whole numbers can also be represented on a number line, where numbers are placed at equal intervals. Zero is usually placed in the middle, and positive whole numbers increase to the right, while negative numbers (which are not part of whole numbers) increase to the left.

5. Whole numbers are important in various mathematical operations and calculations, including addition, subtraction, multiplication, and division. They provide a foundation for understanding more complex number systems like integers, rational numbers, and real numbers.

It is worth mentioning that whole numbers are a subset of the set of integers, which includes both positive and negative numbers, as well as zero.
