calculator
It is a machine invented by modern people that can perform digital operations.
Modern electronic calculator is a hand-held electronic machine that can perform mathematical operations. It has an integrated circuit chip, but its structure is much simpler than that of a computer. Can be said to be the first generation of electronic computers (computers), with weak functions, but more convenient and cheaper. It can be widely used in business transactions and is one of the necessary office supplies.
In addition to displaying the calculation results, there are often overflow instructions, error instructions and so on. The calculator is powered by an AC converter or a battery, which can be charged by an AC converter or a solar converter. In order to save electricity, calculators all use large-scale integrated circuits made by CMOS process.
