Taking control of Donkey Kong Jr., players perform simple arithmetic to learn and practice math. Game modes A and B consist of easy and harder problems where Donkey Kong holds a number on the top of the screen. The numbers 1-9 appear on chains and addition, subtraction, multiplication, and division signs are on island platforms on the bottoms of the screen. Players are tasked to use the numbers and add/multiply/subtract to get to the target number.
