Math Problem: The Making Of Zoey Zinger

There is one button on the left hand corner that is misleading because it seems to have a function but doesn't.

If one answers a math problem incorrectly, it shows the correct answer before moving on to the next math problem. If one gets several problems wrong, it shows the percentage of the problems that one answered correclty. If one gets several problems correct, it shows the percentage and a bee named Zoey Zinger, the game mascot, flyes onto the screen and the narrator says, "Keep on buzzing Zoey Zinger."

It has a high degree of interactivity because one need to continuosly solve the math problems before the time is up.
Not only is it easy to use, but it gives you a mini tutorial at the beginning of what each button does and how to use
