How it works
Start with the ones, then the tens, then the hundreds.
If a place has too many, bundle ten into the next place. If too few, break one from the next.
Check your answer.
Worked examples
No breaking
- 833 − 114 = ?
- Work ones, tens, hundreds.
- Nothing needs to break.
- So the answer is 719.
A zero in the middle
- 502 − 47 = ?
- There aren't enough ones, so look at the tens.
- Break a ten, and you may need to break a hundred first.
- So the answer is 455.
Break a hundred
- 525 − 33 = ?
- The tens are too few, so break one hundred into ten tens.
- Then take away each place.
- So the answer is 492.
