MG-9025 12 Digits Electronic Calculator - White

An electronic calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics. The pocket sized devices became available in the 1970s, especially after the first microprocessor, the Intel 4004, developed by Intel for the Japanese calculator company Busicom. They later became used commonly within the petroleum industry (oil and gas). Modern electronic calculators vary: from cheap, give-away, credit-card-sized models to sturdy desktop models with built-in printers.
