About the Mental Math Test

Mental arithmetic is the ability to work out a sum in your head without writing anything down. This test gives you 30 seconds and a stream of problems, starting with easy two-digit addition and getting harder the more you get right.

Type your answer and press Enter. A wrong answer resets your streak but does not end the test, so keep a steady pace. Your grade is based on the number of correct answers, with your accuracy and longest streak shown alongside.
