Using three MSI circuits, construct a binary parallel adder to add two 12-bit binary numbers. Label all carries between the MSI circuit.

Logic circuit Multiplexer In this question I used same question for two different cell scheme types First one I used up to down cell scheme like 0 4. 12 8 1. 5. 13. 9 3. 7. 15. 11 2 8. 14. 10 Function is €m(0,5,6,8,9,10,14) I got in the letter below I0=B’ Means B complement I1=A’B+AB’ I2=A+B I3= 0 But second k map cell scheme I used like this right to left for the same function 0. 1. 3. 2 4. 5. 7. 6 12. 13. 15. 14 8. 9. 11. 10 But I got different answers for the same function I0=A’B’. I1=A’B+AB’ I2=AB’. I3 = A’+B’ Only i1 I got the same but isn’t which ever cell scheme you use the answer shouldn’t be different right or I do it wrong please look the picture carefully give brief explanation where did I understand wrong

Q1: Can you clearly show the answer to both parts of this question

Q2
