This game was made for my son who does not study very hard but likes playing games with iPhone. This application is to help players strengthen their abilities to do mental calculations with enjoyment. Players are to do math in their heads until they answer correctly 10 consecutive questions and they compete for the time spent to complete calculations. Good for elementary school pupils. Helpful for grown-ups who always use calculators and/or spreadsheets for mental exercises also. Three levels available - Elementary, Intermediate and Advanced. Scores are ranked by the time spent and automatically recorded, then top 10 scores are displayed. Furthemore, your score can be posted to your Twitter by Twitter linkage function. Your score is not automatically posted, so you can post only good scores. This application avoids very easy questions such as 10+3. You can pass up to 3 times per game so you will not drop by the wayside.
