_________________________
Math fun is an educational game which can be played by one or two players. Each player controls a gorilla which is wandering through the jungle.  As the gorilla walks on, it will encounter a creature which has a math problem with it. You need to enter in the correct answer to the problem as quickly as possible. If you get the answer correct, your gorilla may continue on. If you get the answer wrong, then your gorilla must jump into the river. Your gorilla is unable to leave the river and continue on until you answer another math problem correctly. The goal is to correctly answer as many of the problems as you can in the shortest amount of time. The game includes eighteen different levels of difficulty which can be set individually for each player.


PRODUCTION HISTORY:

Although it has a higher production number than Word Fun, Math Fun was released first -- it was one of the original four cartridges test marketed in 1979.

Initially, the solutions for math problems had to be entered ones column first. For example, when subtracting 5 from 24, the solution, 19, would have to be entered as 9, then 1. While this was designed to duplicate how people solve problems with pencil and paper, many customers complained; intuitively, they wanted to simply press in 1 then 9. A running change was ordered so that later copies of the cartridge use this intuitive method of entry, instead.

The Electric Company Math Fun was recycled as the game Math Master on the Learning Fun I cartridge from INTV Corporation.
