After you've answered a problem, reset it. Each time you reset the problem,
the left counter increases for a correct answer; the right shows the number of subtraction math problems you've done.
The "Correct!" mark does not appear when keeping score. If the answer is incorrect, then the right answer will be displayed when you reset the problem.
When finished, your score will be shown.
The spinning math symbols mean we're waiting on the server - if it spins too long, try pressing the reset button again.
