Although it has a higher production number than , 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.
