What is a calculator?
A calculator is a device that performs arithmetic on numbers. Basic calculators
can do only addition, subtraction, multiplication and division mathematical
calculations.
However, more sophisticated calculators can handle, square roots, logarithms,
trigonometric functions and hyperbolic functions. Internally, some calculators
perform all these functions by repeated addition processes.
The evolution of the calculator
Most calculators these days require electricity to operate or are battery-powered
calculators. Calculators work by performing programmed functions based on
numerical inputs.
Before the electronic calculator (circa 1970), a more primitive calculator, the slide
rule, was commonly used. It consisted of a slat of wood called the slide that could
be moved in and out of a reinforced pair of slats. Both the slide and the outer pair
of slats had calibrated numerical scales.
