How this test works
This test measures arithmetic fluency: how quickly you can work out simple number facts. You have 60 seconds. Problems mix adding, subtracting, multiplying and dividing, and every answer is a whole number that is never negative. Type the answer with the keypad on screen or your keyboard; the next problem appears as soon as your answer is right. Your score is the number of problems you solve in time. Psychologists have studied timed mental arithmetic for decades.
