From Yohann C. Taieb:
A very fun and practical way to exercise your brain and your math skills. An excellent way to test your skills in mathematics and/or learn math in a fun as well as develop your fast reflexes!Basic math operations are simple, however, once you start getting into these multiplications and divisions, watch out! You are also playing with a time constraint!Show Professor Cat Math that you can take his math challenge and pass his class.
