Math Boxing Prime Composite

This isn't your dad's punching bag as it will throw punches if you don't answer the prime/composite request correctly or you take too long.

Look at the prime/composite request on the left and click on the correct answer on the right. You'll lose a glove (life) if the countdown timer reaches zero before you answer or you answer incorrectly. As you complete a level the numbers get larger and the time gets shorter! See how far you can go.
