From Paul Golding:
Give your brain a daily workout with this challenging maths game. Score as many points as you can in the time limit and try to beat your personal best.A mathematical problem is displayed at the top of the screen and you are presented with 9 possible answers. Answer as quickly as possible but don't rush as you lose 2 points for every incorrect guess.The game can be configured for young children with small numbers and a long time limit (or no time limit at all to reduce the pressure). Alternatively select any combination of larger numbers and different timers to create a great challenge for adults.The user can also change whether the game supports addition, subtraction or both. This adds to the challenge or allows a simpler configuration for young children.
