I chose a scientific calculator because it is cheaper than a graphic calculator from Texas Instruments but more complex than a simple calculator. This calculator has three main parts: it has the battery which is connected to the circuit board by two wires which are both positive and negative. The buttons all are recorded when typed into the circuit board and then calculated. After it has calculated the problem the information is transferred to the screen and can be seen for the user.
