A '''calculator''' is a device for performing arithmetical operations, such as [[addition]] or [[multiplication]]. Most present-day calculators are [[electronics|electronic]] devices, but the first calculators were mechanical. One of the first calculators was designed by [[Blaise Pascal]].

Later, electromechanical calculators were constructed. Electronic calculators, first using [[vacuum tube]]s, then [[transistor]]s, and finally [[integrated circuit]]s ("chips"), have become small, cheap devices, that often have the capabilities of a full-fledged [[computer]].
