Mental Math Trainer

Introduction to the tool and how to use it

A timed mental arithmetic drill: pick addition, subtraction, multiplication, division or random, choose one of four number ranges from 1-20 up to 1-9999, or set your own minimum and maximum. Answer with the on-screen keypad or your keyboard and press Enter. A correct answer scores a base value plus the seconds you had left, so the faster you are the more you score; a wrong answer or a timeout reveals the solution and resets your streak. Time, score and best score are all tracked.
