My most active subscriber asked me to show how to make a calculator with circuits and so I begin that journey with this video. To make a calculator you need to understand Transistors as well as Transistor Gates. I make 4 circuits, one to demonstrate how transistors work as well as NOT, OR & AND Gates.
