Scientific calculator was the first company to produce one (Casio fx-7000G). Scientific calculator A scientific calculator is a type of electronic calculator, usually but not always handheld, designed to calculate problems in science, engineering, and mathematics. They have almost completely replaced slide rules in traditional applications, and are widely used in both education and professional settings. In certain contexts such as higher education, scientific calculators have been superseded by graphing calculators, which offer a superset of scientific calculator functionality along with the ability to graph input data and write and store programs for the device. There is also some overlap with the
Sumitomo Electric Industries in optical transmission networks and optical communication devices. The Sumitomo Electric Group's electronics division supplies various products to manufacturers of smartphones, flat-screen televisions, and other highly advanced electronic goods. Products include base material, wiring, and components for compact and lightweight devices with high functionality, such as flexible printed circuits (FPCs), electronic wires, heat-shrinkable tubing, fine polymer products, and compound semiconductors. Capitalizing on compound semiconductor development and manufacturing-knowledge accumulated over many years, Sumitomo Electric succeeded in developing and mass-producing the world's first gallium nitride substances. Sumitomo Electric also continues to be the leading manufacturer of composite semiconductors (GaAs, GaN, InP), which
