Practice time 4g

1. Find the sum of the following. One has been done for you.

(a) tens Ones (b) tens Ones (c) tens Ones (d) tens Ones
1 2 1 3 1 4 1 1
+ 4 + 1 + 5 + 2

1 6
(e) tens Ones (f) tens Ones (g) tens Ones (h) tens Ones

1 3 1 8 1 2 1 6
+ 3 + 1 + 6 + 2

2. Add and observe the answer.

(a) 10 + 4 = (b) 10 + 5 = (c) 10 + 8 =

(d) 10 + 3 = (e) 10 + 9 = (f) 10 + 2 =

(g) 10 + 6 = (h) 10 + 1 = (i) 10 + 7 =

Adding Zero (0)

There is no bird 4 birds come and sit on the How many birds are there

on the tree. tree. on the tree now?
Clearly, 4.

So, 0 + 4 = 4.
Similarly, 4 + 0 = 4

When we add any number to zero or zero to any number, we get the same number.
