Whole Numbers

Whole Numbers

Whole numbers are numbers that do not contain a fraction or decimal and only consist of positive integers. Whole numbers start from 0 and include 1, 2, 3, 4, 5, 6, and so on. Whole numbers do not include negative numbers or decimals.

Example: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, etc.

Whole Numbers on Number Line

Whole numbers on a number line are the numbers that are positive and non-fractional. They are often represented by dots or tick marks on the line and can include 0, 1, 2, 3, 4, 5, and so on. They are used to illustrate the magnitude and order of numbers and can be used to compare, add, and subtract numbers. The number line is a visual representation of the ordered set of whole numbers and can help students understand the relationships between numbers.

The representation of whole numbers on a number line is shown below:

For example, if we want to represent 0, 3, 5, 8, 10 on the number line then we will represent it by dots on the number line as shown below, and the distance between each dot represents the difference between the numbers.

Whole Numbers with Operations

Operations on whole numbers can include:

1. Addition:  Adding two or more whole numbers to get a sum.

Example: 5 + 3 = 8

2. Subtraction: Subtracting one whole number from another to get a difference.

Example: 10 - 5 = 5

3. Multiplication: Multiplying two or more whole numbers to get a product.

Example: 3 x 4 = 12

4. Division: Dividing one whole number by another to get a quotient.

Example: 20 ÷ 4 = 5

5. Modulo: The remainder when one whole number is divided by another.

Example: 10 % 3 = 1 (10 divided by 3 is 3 with a remainder of 1).

NOTE: The modulo operator is represented by the percent symbol %.
