Disappearing Math: Addition is a new unique way to both sharpen basic math skills, and also exercise your brain.

With the Disappearing Math quizzes, the math questions disappear before your eyes, forcing you to both memorize the question, and complete it in your head before answering. This way, you are actually computing the calculation in your memory, as opposed to associating the answer by sight.

Features Include:
-3 Levels of Addition (single digit, double digit, triple digit)
-3 Disappearing Speeds to select from
-3 selectable quiz lengths (10, 25, 50 questions)
-"Practice Mode" - disables the disappearing feature for the quizzes

Bonus Feature! - Flash Card Mode, using the same 3 levels of addition with basic flash cards rather than quizzes.
