Yupana Lite

At School. How did you learn the Multiplication, Division, Subtraction and Addition Tables? Do you remember that you had to memorize them? Do you really believe that you are good enough with mental calculation and not using your fingers? We challenge you to solve our arithmetic exercises with one simple idea, we provide you one number and operation(s), and you are free to decide the combination of numbers available, in order to solve the exercises. With Yupana you will be able to improve your mental calculation skills, that is the main reason that we encourage you to try it and leave out the doubt.
