As we have discussed earlier, number line can be used to perform various mathematical manipulations like addition, subtraction and multiplication.

The focus of the post is to perform number line additions. We will discuss different kind of examples so that there will be no room of doubt among the students.

But first the question is, why should we use number line for addition?
Its because this tools will help you to understand the concept of addition better. If you are a student who is facing difficulty to do addition of numbers, i will strongly urge you to first practice addition using number line for better conceptual understanding.

Now its time to see various examples of additions using step by step method.

(a). Add 9+5 using number line
Steps:
1. First we will mark the number 9 and start hopping from there towards right
2. As we have to add 5, so we have to hop five times
3. After five hopping we will reach number 14 which is our answer

(b). Add 10 + 3 using number line
Steps:
1. First we will mark the number 10 and start hopping from there towards right
2. As we have to add 3, so we have to hop three times
3. After three hopping we will reach number 13 which is our answer

(c). Add 7 + 8 using number line
Steps:
1. First we will mark the number 8 and start hopping from there towards right
2. As we have to add 7, so we have to hop seven times
3. After seven hopping we will reach number 15 which is our answer

(d). Add 4 + 5 + 6 using number line
Steps:
1. First we will start with the highest number which is 6
2. Then we will add second highest number 5 by hopping 5 units towards the right
3. Then we will add smallest number 4 by hopping 4 units towards the right
4. 15 is the right answer

(e). Add 9 + 3 + 6 using number line
Steps:
1. First we will start with the highest number which is 9
2. Then we will add second highest number 6 by hopping 6 units towards the right
3. Then we will add smallest number 3 by hopping 3 units towards the right
4. 15 is the right answer

I hope the concept of adding number line is clear for you.
In the next set of posts we will be understanding subtraction and multiplications using number lines
