Casio fx-85GT PLUS scientific calculator

The Casio fx-85GT PLUS is a widely recognized scientific calculator, particularly popular in the United Kingdom and Ireland for use in secondary education and examinations. Originally introduced around 2010 as part of Casio's efforts to provide student-friendly tools with natural textbook displays, this specific model features 260 functions and 'Natural-V.P.A.M.' technology, which allows mathematical expressions to appear exactly as they are written in textbooks.

Historically, this model was manufactured in China. Although it was officially discontinued by Casio in late 2018 to make way for the updated 'ClassWiz' (GTX and later CW) series, it remains a common sight in classrooms due to its durability and solar-plus-battery power system. The brand Casio itself is a cornerstone of Japanese electronics innovation, founded in Tokyo in 1946. Today, the brand continues to be owned and managed by Casio Computer Co., Ltd., maintaining its global headquarters in Japan and operating through various regional subsidiaries like Casio Electronics Co. Ltd. in the UK.
