Features of the Math Trainer

	Designed for high speed so that you get lots of practice.
	Timed Workout style just like athletes use.
	Cutoff Time pushes you to quickly remember, not count to get an answer.
	Shows you the correct answer when you get it wrong.
	Remembers your performance (during the session, but not between sessions) so that it gives you more practice on your weaknesses.

Workout Time

You can make good progress by having 3 sessions of 5 minutes every day. But when you just want to practice as you feel choose "1 day".

Cutoff Time

The Cutoff Time is there to help you!

It means you only have a few seconds to answer each question.

At first it seems hard, but as you start to remember you get better and better. And at high speed you get lots of practice.

(Without the cutoff time you can count to get each answer and never truly learn your tables.)

Choose 4 seconds for best effect.
