Subtraction of 3 Digit Numbers (With Borrowing)
Subtract 128 from 645
Step1. Place the number one below the other.
Step2. Subtract the ones
As 5 is smaller than 8, we cannot subtract 8 from 5. So, 1 ten is borrowed from the tens column.
Now, 1 ten = 10 ones, which means 10 ones + 5 ones = 15 ones.
We have 15 ones and we can subtract 8 ones from 15 ones.
15 ones – 8 ones = 7 ones
7 is written in the ones column of the answer
Step3. Subtract the tens
After borrowing 1 ten from tens column, we have 3 tens (4 -1=3 tens) in the tens column.
Now subtract the tens
3 tens – 2 tens = 1 tens
1 is written in the tens column of the answer
Step4. Subtract the hundreds
Now subtract the hundreds
6 hundreds – 1 hundreds = 5 hundreds
5 is written in the hundreds column of the answer
