This course, taught by Mark Englander, who studies Computer science with Mathematics at the University of Cambridge, will cover the basics of logic within in circuitry and will finish with some details on simulating a basic calculator circuit. We start by looking at the binary representation of a number. We then move on to the basic gates within circuitry logic, AND, NOT, OR and XOR. Finally we build our calculator, using the skills we developed from the first two sections.
