Subtract 3-digit numbers
On this page children practise subtracting three-digit numbers including ones, without the formal written column method. Start with the short method and the examples, then use the online practice or print a worksheet with answers.
How to solve this
- Subtract three-digit numbers column by column from right to left; borrow from the next column when needed.
- Each borrow reduces the lending column by 1 and adds 10 to the borrowing column.
- Check by adding: answer + subtracted number must equal the starting number.
Examples
598 − 347 = ?
251
795 − 428 = ?
367
