3. The following figure shows the four-bit Adder-Subtractor. Your inputs for this combinational circuit are A = 8, B = 5 and M = 1. What is the outputs S3, S2, S1, and S0? You have to show how to get the outputs by indicating each carry bit. (Note: You should show all the steps to receive full credits)

This is a practice problem I am having a little difficulty with understanding. Thank you for the help.

For the 4-bit parallel adder shown, input: A4 A3 A2 A1 =1110, B4 B3 B2 B1 =1011, and Cin=0.   Determine the sum output Σ 4 Σ 3 Σ 2 Σ 1. Determine the carry out C4.
