solve the math questions to earn points, if you get a question wrong you lose a health point, if you lose all your health you fail. There is 3 difficulty levels: 1: add and subtract with numbers from 0-9 2: add, subtract, and multiply with numbers from 0-99 3: add, subtract, multiply, and divide with numbers from 0-999
there is a bug where division shows up in difficulty 1 & 2 but only rarely
