From Nintendo: Learning can be fun, especially when you play along with Donkey Kong Jr. Practice addition, subtraction, multiplication and division by directing Junior, a cute little monkey who must climb up and down vines to collect numbers and math symbols to solve the math problems his father gives him. Compete with a friend in a race to solve problems in Game A or add more challenge with Game B. Of course, you can also practice on your own. This game is perfect for younger players who are looking for a fun and easy way to develop their math skills.
