About this quiz
A one minute sprint of subtraction. Forty questions is more than most people finish, so the score is simply how far you get before the clock runs out.
- Both numbers are at most 24, and every answer is a whole number from 1 to 12.
- A wrong answer costs time but does not end the run.
