Quick mental arithmetic can carry only a few personalities. Maybe it's here in the individual predisposition, but you can always pull up the skills. Quick Math - a simple application that will make you the king of arithmetic.
After starting you will find yourself in the main menu. You can select the mode and level of difficulty, as well as delve into the settings. An interesting fact is that the Quick Math recognizes handwriting: a response is issued on the screen, and the application determines whether it is correct.
If a standard profile for some reason did not come to you liking, you can always create your own. There is even the option avatar selection, but the practical benefits of this I do not see.
We turn to the most interesting - the computational process. I would advise to choose mixed mode. So you can work out at once over all actions. As I mentioned, Quick Math recognizes text. And he does it fairly efficiently. Of course, the flaws do occur, but not as often.
At the top of the screen there is a timer. He is not there by accident: after completion of phase results are stored. Progress can be seen in the graph. At the maximum level of difficulty to play really hard.
