Donkey Kong Jr. Math (Nintendo, 1985) - NES Gameplay

The game features one player and two player modes. In the one player mode, the objective is to enter math answers in order to receive points. In the two player mode, each player applies a math operation (addition, subtraction, multiplication, or division) to the number they have to make it another number, trying to eventually reach a mutual goal number. However, signs and numbers are on the same field for each player, and they must race to reach the final number.
