The answer is 65,359. A child who answers 9,344 probably added instead of multiplying.
- 2,906×2=?
The answer is 5,812. A child who answers 2,906 probably counted one group too many or too few.
- 9,877×4=?
The answer is 39,508. A child who answers 6,288 probably forgot to carry.
- 93×74=?
The answer is 6,882. A child who answers 6,312 probably multiplied the tens and the ones but not the rest.
