Quick Math is a challenging and addictive math quiz game in which you have to rapidly decide whether the basic arithmetic statements displayed on screen are true or false.
Besides being a fun addictive game, it will train your brain to do faster mental calculations.
The basic arithmetic calculations are covered: addition, subtraction, multiplication, and division.
At first you have "plenty" of time to answer the quizzes but the game becomes increasingly difficult. If you give fast answers, you receive small time bonuses for the quizzes to come.
