 The game features one and two player modes , both of which are single screen . In the first mode , the objective is to enter math answers in order to receive points . These questions include addition , subtraction , multiplication , and division . In the two player mode , two players control two characters as they race to create a math formula to reach the number shown by Donkey Kong , incorporating platform gameplay . The mechanics are similar to Donkey Kong Jr . ; players climb vines to reach higher areas in order to collect numbers scattered around the area . In order to complete mathematics problems , players must collect at least three things : the first number , the symbol necessary to reach the number shown by Donkey Kong , and the second number . When the game features a high number , such as 66 , players must collect multiple numbers and mathematics symbols in order to reach this . For example , players could choose a nine , a multiplication symbol , and a seven , followed by an addition symbol and a three to reach the number 66 . The two player game have two different levels , Calculate A and Calculate B. Calculate B is more challenging : Donkey Kong can ask for negative numbers , and the absolute values of the target numbers are in the hundreds instead of the tens .
