This lesson will teach you how to add numbers on a number line.
Counting on a number line is a fun way for a youngster to learn how to add numbers together.
The use of a colourful number line to add numbers piques the children’s attention.
The word “addition” denotes “plus”. “+” is the sign for addition. On the number line, add the numbers together. This strategy is only utilized when there are a few people. The number line in lower grades starts at zero. The number line is a line that starts at zero and has numbers 1,2,3,… at equal intervals along with it. Because you may leap from one number to another, it’s employed in addition, subtraction, and multiplication.
The addition of a number line allows us to conduct additional operations on tiny numbers graphically. A number line is a visual depiction of numbers on a straight line with increasing value as we travel from left to right. A number line may be used to execute various mathematical operations such as addition, subtraction, multiplication, and division. In this post, we’ll study more about adding on a number line.
What is Number Line?
- The graphical depiction of numbers such as fractions, integers, and whole numbers put out equally on a straight horizontal line is known as a number line. A number line is a tool that may be used to compare and order numbers as well as to conduct operations like addition and subtraction.
- On a number line, all sets of numbers, such as natural and whole numbers, are represented. (0, 1, 2, 3,4,5,6,……) is an example of a set of whole numbers, whereas natural numbers include: 1, 2, 3, 4, 5, 6,…
- There are three fundamental pieces to a number line. The origin is commonly plotted with zero in the center. This mnemonic might help you recall that the origin is zero: “The origin of most things is nothing.”
Example:
Subtract -2 – (-4), for example:-
On the number line, look for the number -2. Move 4 steps to the right for a total of 2.
A number line can also be used for multiplication. To accommodate the values, you must draw a larger number in this scenario. Depending on the numbers being multiplied, you can draw a number line by selecting a suitable scale.
Multiplying 5 by 3 is an example:-
Start counting from the origin and go 5 steps three times to solve this issue.
In this situation, the right answer is 15
How to Add 3 Numbers using Number Line
- Using the Number Line to Add and Subtract Positive and Negative Numbers.
- Using visual interpretations to add numbers on a number line is a fun method to see how numbers are added.
How to Add Numbers on the Number Line in Steps-
As shown in the illustration below:
When we add a positive integer, we move the point to the right of the line of numbers.
Adding a negative number, on the other hand, requires moving the point to the left of the number line.
We can use the number line to help us add:
| 5 + 3 = 8 |

Concluding Remark
- It is easy to calculate digits for the children.
- Children naturally advance from counting to basic addition, but there is a critical turning point along the road. It happens when kids realize they don’t have to count all the way back to one.
- For addition and subtraction, number lines give a conceptual method. It’s tempting to dismiss them as a sort of crutch for the downtrodden, but this isn’t the case. They’re vital, according to research, since they encourage strong mental arithmetic skills.
