Test your brain against the best, or simply practice using custom settings. Great for keeping the brain active!!!

Choose from 3 configurable difficulty levels or choose a custom setting and determine what maximum calculations to use. Get the answer correct then get a point, get it wrong and lose a point. Simple!!!!

See if you can get top of the leader board!!! one of the 12 leader boards available. In order to use the leaderboard functionality you must have a game centre account. So if you have not set one up the select the game centre app icon and create.

The leaderboard used is dependent on the settings selected, I.e 3 levels will all use a different leaderboard, for each level choose between addition only, multiplication only, subtraction only or all 3. Each of these will result in a different leaderboard being used. So become the best in the world....

See if you are as quick as you think....
