Subtraction with Borrowing

Let us learn to subtract by borrowing.

To subtract 28 from 64.

T O First we subtract digits in ones column.
6 4 Here 4 < 8

– 2 8
So what should we do?

T O
We borrow 1 ten from tens column. So 4
6 1 4 becomes 14.

– 2 8 Then 14 – 8 = 6
6

T O
Because we borrow 1 from Tens number 6.
5 6 1 4 So it remains 5.

– 2 8 Now 5 – 2 = 3
3 6 Therefore, 64 – 28 = 36

Subtract the following by borrowing method. One is done

for you

T O T O T O T O

7 8 1 4 4 8 2 5 3

– 2 3 – 2 5 – 5 9 – 2 6

5 8

T O T O T O T O
8 4 5 5 3 2 3 8

– 6 7 – 3 8 – 1 4 – 1 9
