Have been introduced five levels of difficulty. Reached only one fifth if you enable addition, subtraction, division and multiplication with a high degree of difficulty in each. Do you dare? Expanded ability to select the difficulty level of operations. Extended setup menu to select operations of addition, subtraction, multiplication and division. Fix minor bugs. Upcoming versions, revisions to the statistics.
