What is the difference between casio fx-82es plus and fx-82za?

Well, darling, the main difference between the Casio fx-82ES Plus and the fx-82ZA is that the ES Plus model is solar-powered, while the ZA model relies on battery power. Additionally, the ZA model has a slightly different design and some updated features compared to the ES Plus. But hey, at the end of the day, they both do the same job of crunching numbers, so pick your poison and get calculating!
