Step 3. Now, subtract the hundreds.

7 – 2 = 5 hundreds Get it right!
H t O H T O H T O

8 13 7 15
7 9 3 4 8 5 4 8 5
– 2 4 6 – 2 1 9 7 – 2 1 9 3
2 6 6
2 7 4
5 4 7
Thus, 793 – 246 = 547
regrouping hundreds

We know that 1 hundred = 10 tens
So, we borrow 1 hundred from the hundreds place when there are not sufficient

tens to subtract at the tens place.
Let us understand it through an example.

example 2: Find: 428 – 182.
Solution:

Step 1. Subtract the ones. Step 2. Subtract the tens.

8 – 2 = 6 ones H t O

H t O 3 12
4 2 8

4 2 8 – 1 8 2
– 1 8 2 4 6
6 Since, 8 < 2, so regroup.

4 hundreds + 2 tens
= 3 hundreds + 12 tens

12 – 8 = 4 tens
Step 3. Subtract the hundreds.

3 – 1 = 2 hundreds Think and Answer

H t O Put the least digit in the blanks so that
you need to regroup and subtract them.
3 12 1. Tens into ones 2. Hundreds into tens
4 2 8 H T O H T O
– 1 8 2

2 4 6 – 7 5 6 – 4 2 8

5 2
Thus, 428 – 182 = 246
