Donkey Kong Jr. + Jr. Math Lesson
From the Super Mario Wiki
Donkey Kong Jr. + Jr. Math Lesson (ドンキーコングJR.+JR.算数レッスン) 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. This game was released with a Sharp C1 TV (with built-in Family Computer), and is a very rare find.
