This game can also be used to teach children math. The gameplay is simple, but it is harder to play than you might think! A numerical expression will appear on the screen, and you will have a limited amount of time to solve it and choose the correct answer from 4 options. Each correct answer earns you one point, and your final score will be based on the number of correct answers. You lose if you choose the wrong answer or if time runs out! As mentioned, the game seems easy at first, but with each level it becomes harder and harder.
