You can use this program to train and test the knowledge of children of primary school age or older. The program has four modes: addition, subtraction, multiplication and division. Each mode of the program has individual settings, which allow to control the complexity level. In case of difficulty it is possible to get a hint. Results will be stored in three categories: right answers, answers with hints, wrong answers. Also, you can see a whole history of the answers and the final grade of the child.
