for the part where it says record, you don't have to. just summarize the main points and I will do the recording

Part 3) Draw the following circuit using Logsim software: Number B Number A 0 0 0 Subtract? c out cout MUX +/- a) What does this circuit do? Explain the different parts of the circuit. b) Simulate the circuit and check its operation. c) Record a 1 min video and upload on Youtube that shows the all the steps you used to build the circuit in logsim. Include in the video also a quick simulation of the circuit
