Donkey Kong Jr. Math

Donkey Kong Jr. Math was the third game released in the Donkey Kong series, and the second to feature Donkey Kong Jr. It was released in 1983 for the NES. Donkey Kong will hold up a sign, and Donkey Kong Jr. must find the numbers and math sign to get to that number to get a point.

Donkey Kong Jr. Math was met with negative reviews and the worst selling launch-title for the system, yet was later released as a compilation called Donkey Kong Jr. + Jr. Math Lesson which included both Donkey Kong Jr. Math and Donkey Kong Jr. This game was recreated as an obtainable item in the game Animal Crossing and it was re-released the first time on the Virtual Console for the Wii (500 Wii Points) on September 3, 2007 and re-released the second time on the Wii U ($4.99) in North America on August 28, 2014.

Donkey Kong Jr. Math was the only game to be released under the "Educational Series" label of North American NES titles. While Donkey Kong no Ongaku Asobi was intended to be released around the same time, it was canceled and no other educational games in the Donkey Kong series were made.

Gameplay
The game features a one and two player mode. In the single player mode, the player's goal is to enter the answers to mathematical questions in order to receive points. The questions include addition, subtraction, multiplication and division. In the two player mode, both players control two Donkey Kong Juniors (a normal brown one and a pink one) that are on a race to create a math formula that equals the number shown by Donkey Kong. The gameplay is similar to that of Donkey Kong Jr.; players climb vines to reach higher areas. To create the math formulas, the player has to collect the numbers and the symbol(s) in the correct order that can be reached by using the vines.
