Let us read the another way to add the objects or numbers.

There are 16 birds on a tree. Soon, 25 more birds come and sit on the
tree. Let us add to see how many birds in all are there now.

For, 16 + 25 we write :

10 1

1 1 1
1 6 10
1 1 1

1 1 1
+ 2 5 10 10
1 1

10 1

1
1
Putting all the s together, 1 1 1
1 6 10 10
we get eleven s of those 1 1 1
1
ten s make one . + 2 5 1 1 1
1
10
And we are left with one . 10 10 1 1
1
1

10 1

1 6 10 10
10
Now, putting together all the s,
+ 2 5 10 10 1 we get four s.
