About Casio
Casio Computer Co., Ltd. is a Japanese multinational electronics corporation headquartered in Shibuya, Tokyo, founded in 1946 by Tadao Kashio. The company revolutionised the calculator industry in 1957 with the 14-A, the world's first compact all-electric calculator, and has remained synonymous with calculators ever since. From its humble beginnings developing the "yubiwa pipe" (a finger ring cigarette holder), Casio evolved into a global electronics powerhouse producing calculators, watches, digital cameras, and electronic musical instruments. The company pioneered digital watches with the 1974 CASIOTRON (the first with automatic calendar), created the iconic G-Shock range (1983), and made the best-selling watch in history - the F-91W (3 million units annually). In the UK educational market, Casio scientific calculators like the FX-83GTCW and FX-85GTCW are the go-to choice for students. These models are approved for use in UK exams including GCSE and A-Level, featuring natural textbook display for easier understanding of mathematical expressions. The GT in the model name indicates versions specifically designed for the UK curriculum. With decades of calculator expertise, Casio combines Japanese precision engineering with user-friendly design, making complex calculations accessible to students at all levels.
