Calculator is a machine invented in modern times that can perform number calculations.
Modern electronic calculators are handheld electronic machines that can perform mathematical
operations. They have integrated circuit chips, but their structure is much simpler than that of
computers. It can be said that they are the first generation of electronic computers (computers),
and their functions are weaker, but they are more convenient and more convenient. It is cheap and
can be widely used in commercial transactions. It is one of the essential office supplies. In

indications, etc. The power supply of the calculator adopts an AC converter or a battery, and the
battery can be recharged by an AC converter or a solar energy converter. In order to save power,
calculators use large-scale integrated circuits made with CMOS technology.
