Calculators

A calculator is an instrument for making calculations. In most cases, the number keys from 0 to 9, the four arithmetic calculation keys of +-÷×, and function keys such as memory are arranged on a square board, and the upper part has a screen that displays the entered numbers and calculation results. . There are two types of calculators: a general one that is mainly used for arithmetic calculations, and a scientific calculator that performs functional calculations such as mathematics, physics, and civil engineering. A feature of scientific calculators is that they have many function keys, including calculus and trigonometric functions. Each product is characterized by its size, number of display digits, types of function keys such as consumption tax and exchange calculation, and presence or absence of dustproof and waterproof specifications.
