Example:
Milan says that he wants to find 8 + 5.
Solution:
Make 10 to add 8 + 5
Let us find this.
![add 8 + 5](https://www.turito.com/learn-internal/wp-content/uploads/2023/07/add-8-5-1024x378.png)
Doubles Plus:
Let us solve 8 + 5 by using doubles plus.
Solution:
8 + 5
= 3 + 5 + 5
= 3 + 10
= 13
Number Line:
We can also solve 8 + 5 by using a number line.
