How to Build a Pocket Calculator
A calculator is an electronic device used for solving mathematical calculations. While it's different from a computer in that it has limited problem-solving ability and can't program, it is much more portable. But you don't have to purchase one at your local retail outlet. With a little knowledge and some extra time, you can build your very own pocket calculator.

1
Design the logical circuit. A logic circuit is a computer switching circuit that consists of a number of logic gates and performs logical operations on data.
-
2
Map the circuit design onto semiconductor materials. Creating a complex design on a tiny material must be an accurate and precise process. The tiny material containing the complex design is called a chip.

The chips are then packed to form a small component, which is the IC or integrated circuit. An integrated circuit, which is also referred to as a microchip or silicon chip, is a miniaturized electronic circuit. It consists of semiconductor devices in addition to passive components manufactured in the surface of a thin substrate of semiconductor material.

4
Perform an online search to help determine the component library needed for the specific IC you're going to use.

After putting the IC in a small board, add the keypad and LED. LED stands for "light-emitting diode," which is an electronic light source. A keypad is a set of buttons arranged in a block that usually bear digits and other symbols but not a complete set of alphabetical letters. The keypad of a calculator contains the digits 0 through 9. It also includes the four arithmetic operations (subtract, add, multiply and divide) with the decimal point and other more advanced functions also present. Place the pocket calculator devices in any configuration you wish. Now group the components and pack them together.
