Entering commands through a computer keyboard

The calculator allows input from any numerical keys found on a computer keyboard: including the top row numbers as well as the standalone number pad on the side.

You may utilize the [Enter] key to insert the equal sign.

To remove the most recent character, press the [Backspace] (arrow) key.
For adding a plus sign, press the [ + ] key located at the top or on the side numeric keypad.

To input a minus sign, make use of the [ - ] key found at the top or the side numeric keypad.

To add the multiplication sign, press the [ ] key on the side numeric keypad.

To input the division sign, utilize the [ / ] key on the side numeric keypad.
You can reset the calculator by using the [Esc] and [Del] keys situated at the top of the keyboard, or the [End] key on the side numeric keypad.

History of calculators

The immediate predecessor to calculators is a mechanical and portable device known as the arithmometer. It was primarily designed for multiplication and division. While the arithmometer can also perform addition or subtraction, it is notably challenging. Due to its operational principle, this early calculator serves as a digital device, which ensures that the outcomes of computations are always completely accurate.
