 Representation of Whole Numbers on Number Line becomes very easy if you read the complete article. Generally, in Mathematics, number lines are considered as straight lines which are horizontal and on which integers are positioned at regular intervals. A number line extends both ends infinitely and a sequence of numbers can be represented on it.

The positive and negative integers can be positioned on a number line on either side of zero. The difference, comparison, and basic arithmetic operations can be easily done on a number line. It is the way of representing numbers visually on the horizontal line.

Representation of Whole Number on a Number Line

On a number line, there are 3 basic parts, Zero is considered as the middle point, numbers on the right side are considered as positive numbers, and numbers on the left side are considered as negative numbers. How to Represent Whole Numbers on a Number Line?

Check out the below steps to Represent Whole Numbers on a Number Line. Follow the steps and draw a number line by representing whole numbers with 100% accuracy.

• Draw a straight horizontal line.
• Mark the middle point and label it as 0.
• To the right of zero, mark the points at regular intervals and indicate numbers as 1, 2, 3, 4…. which are positive numbers.
• To the left of zero, mark the points at regular intervals and indicate numbers as -1, -2, -3, -4…. which are negative numbers.
• The numbers at regular intervals are at a unit distance from one another. Addition of Whole Numbers on a Number Line

We will have the addition of positive whole numbers and the addition of negative whole numbers on a number line. In addition to two positive whole numbers, the final result will be a positive whole number and in addition to two negative whole numbers, the final result will be a negative whole number.

If we add positive whole numbers, then the resultant direction will be on the right side of the number line. Let us consider the below example to understand clearly the addition of positive whole numbers.

Example:

Take the addition of 2 and 4, the result is 6 (2 + 4 = 6). The first number is 2 and the second number is 4 where both the numbers are positive.
First of all, locate the number 2 on the number line and move 4 places to the right which gives 6. If we add negative whole numbers, then the resultant direction will be on the left side of the number line. Let us consider the below example to understand clearly the addition of negative whole numbers.

Take the addition addition of -2 and -4, the result is -6 (-2 + -4 = -6). The first number is -2 and the second number is -4 where both the numbers are negative.
First of all, locate the number -2 on the number line and move 4 places to the left which gives -6. Subtraction of Whole Numbers on a Number Line

We will have subtraction of positive whole numbers and subtraction of negative whole numbers on a number line. On subtraction of two positive whole numbers, the final result will be negative. On subtraction of two negative whole numbers, the final result will be positive.

Subtraction of Positive Whole Numbers

To subtract two positive whole numbers, we must move towards the left side of the number line. Let us consider the below example to understand clearly the Subtraction of Positive Whole Numbers.

Example: Subtract 2 from 4?

Subtract 2 from 4. Here the first number is 2 and the second number is 4 which are positive whole numbers. First, locate 2 on the number line and move to 4 places to the left, the result will give -2. Subtraction of Negative Whole Numbers

To subtract two negative whole numbers, we must move towards the right side of the number line. Let us consider the below example to understand clearly the Subtraction of Negative Whole Numbers.

Example: Subtract 5 from -3?

Subtract 5 from -3. First, locate -3 on the number line. Then move 4 places to the right which gives 2. FAQs on Whole Numbers Representation on Number Line

1. What indicates the numbers placed on the left side of zero?

If the integers are placed on the left side of zero. It indicates the negative numbers.

2. What is the smallest whole number?

The smallest whole number on a number line is zero.

3. How many numbers will be represented on a number line?

The number line can be extended indefinitely on both sides. We can represent as many as numbers required on a number line.

4. What indicates the numbers placed on the right side of the number line and what does it indicate?

If the numbers are placed on the right side of the number line, then those integers are greater than integers on the right side. For example, 4 is placed on the right side of 3, as 3 is less than 4.
