Donkey Kong Jr. + Jr. Sansuu Lesson is a game released for the Family Computer in Japan. It is a compilation of the games Donkey Kong Jr. and Donkey Kong Jr. Math. Despite being a compilation of two games, only parts of both are included. Combining half of the 1- and 2-Player game modes from Donkey Kong Jr. and the +-×÷ Exercise mode from Donkey Kong Jr. Math, the game can cater to classic arcade excitement and arithmetic lessons directed towards the younger set. No other gameplay mechanics or details seem to have changed.
