Drill basic arithmetic facts with these virtual flash cards. Two settings are available—timed and untimed. In the timed setting, the answer will automatically flash and then reappear in a user-determined amount of time after the card first appears. In the untimed setting, the answer will not appear until the user chooses to show the answer.
