Subtraction of 3-digit numbers with regrouping are explained here with examples.

As you borrow from the tens column, you can also borrow from the hundred column.

Notice:

1 ten = 10 ones

1 hundred = 10 tens


Solved examples for subtracting 3-digit numbers with regrouping:

1. Subtract 674 – 458

Step I: Arrange the numbers vertically.

Step II: Subtract the units column. Since 8> 4 and we cannot subtract 8 from 4, we regroup 7 tens and 4 ones. Well, 7 tens + 4 ones = 6 tens and 14 ones. 14 – 8 = 6 ones

Step III: Subtract the tens column. 6 – 5 = 1 tens

Step IV: Subtract the hundred column. 6 – 4 = 2 hundreds.

Subtraction of 3-digit numbers with regrouping

So 674 – 458 = 216

2. Subtract 747 – 489.

Step I: Arrange the numbers vertically.

Step II: Subtract the units column. Since 9> 7 and we can’t subtract 9 from 7, so we’re grouping 4 tens and 7s. Well, 4 tens + 7 ones = 3 tens and 17 ones. 17 – 9 = 8 ones

Step III: Subtract the tens column. Since 1 tens is regrouped in units, we have 4 – 1 = 3 tens. We can’t subtract 8 from 3. So we group 7 hundreds and 3 tens. Well, 7 hundreds + 3 tens = 6 hundreds and 13 tens. 13 – 8 = 5 tens

Step IV: Subtract the hundred column. 6 – 4 = 2 hundreds.

Subtract 3-digit numbers with regrouping

So 747 – 489 = 258
