The mistakes behind most wrong answers
A wrong answer in mixed numbers is rarely random. These are the ones that come up most often, each on a real problem — worth knowing before you mark a sheet, because the fix for each is different.
- 528−118=?
The answer is 418. A child who answers 4116 probably changed the bottom number too.
- 558−148=?
The answer is 418. A child who answers 428 probably counted one too many or too few.
- 348−218=?
The answer is 138. A child who answers 538 probably added instead of taking away.
- 416+126=?
The answer is 536. A child who answers 336 probably took away instead of adding.
