14 Step 5: Subtract the remaining ten thousands.
5 11 3 4 12
6 1 4 5 2 5 – 3 = 2

– 3 2 1 7 9
2 9 2 7 3

So, 61,452 – 32,179 = 29,273.
A Challenge!
Example 5: Subtract 40,856 from 92,714.
Complete the pattern.
Solution: TTh Th H T O 6 – = 5

16 10
1 6 0 14 60 – = 50
9 2 7 1 4
600 – = 500
– 4 0 8 5 6
6,000 – = 5,000
5 1 8 5 8
60,000 – = 50,000

So, 92,714 – 40,856 = 51,858.
Example 6: Subtract 2,69,358 from 5,40,267. Write the problem with the answer in words.

Solution: L TTh Th H T O

5 4 0 2 6 7
– 2 6 9 3 5 8

2 7 0 9 0 9

So, 5,40,267 – 2,69,358 = 2,70,909.
Writing in words, we have:

Five lakh forty thousand two hundred sixty-seven minus Two lakh sixty-nine
