Calculator

A calculator is typically a portable electronic device used for calculations, from basic arithmetic to complex mathematics. Solid-state electronic calculators appeared in the early 1960s, and pocket-sized models became available in the 1970s. General-purpose, scientific and graphing calculators serve different needs. Although dedicated calculators remain widely used, calculator functions are also included in smartphones, tablets and other devices.
