Order in Addtion
and are 7 bats.
So, 3 + 4 = 7
This is an example of Horizontal method .
3
+ 4
7
This is called Vertical method .
Similarly, 3 + 4 = 7 or 4 + 3 = 7.
So change in order does not change the sum.
Add in two way.
3 3
+ 4 + 6
4 + 3 = 6 + 3 =
7 5
+ 2 + 3
2 + 7 = 3 + 5 =
1 7
+ 6 + 1
6 + 1 = 1 + 7 =
