CALCULATOR
This calculator has a perfect design that maximizes the size of the buttons and display, with a great layout for fast and easy calculations. Modern electronic calculators contain a keyboard with buttons for digits and arithmetical operations. Some even contain 00 and 000 buttons to make large numbers easier to enter. Most basic calculators assign only one digit or operation on each button. However, in more specific calculators, a button can perform multi-function working with key combination or current reckoning mode.
