Learning powers and exponents is normally not easy or even frustrating.
With the Powers and Exponents game it suddenly becomes fun to practise those numbers! You start with three lives and you lose a life each time you get the wrong answer. You also play against time, so every 20 seconds you lose a life if you havent reached the next level at that point.
As you continue the game gets harder and harder, so dont expect to get bored with Powers and Exponents!
