Step 2. Subtract the tens. t O Subtract the

4 tens are left. 4 12 ones first, then
subtract the
So, 4 – 3 = 1 ten 5 2 tens.

Write 1 in the tens column. – 3 6
1 6
Thus, 52 – 36 = 16

example 2: Find: (a) 82 – 48 (b) 71 – 59

Solution: (a) t O (b) t O Think and Answer

7 12 6 11 1. What is 3 tens less
8 2 7 1 than 70 ones?
– 4 8 – 5 9 2. What is the number

3 4 1 2 just after 95 – 52?

Thus, 82 – 48 = 34 Thus, 71 – 59 = 12

1. Find the difference.

(a) t O (b) t O (c) t O (d) t O
4 5 3 0 2 7 4 0

– 8 – 4 – 9 – 5

2. Subtract the following.

(a) t O (b) t O (c) t O (d) t O
6 0 6 1 4 0 9 0

– 2 5 – 4 4 – 1 8 – 2 1

(e) t O (f) t O (g) t O (h) t O

2 5 5 1 5 2 7 2
– 1 6 – 1 7 – 2 8 – 2 4
