4. (a) Using 2s complement and 6-bit registers, can the operation ((+32) + (+32)) be executed to give the correct answer? If yes, do the operation, showing clearly the steps and result of the computation. If not, explain clearly the reasons why not. (b) Using 2's complement and 6-bit registers, can the operation ((-1) +(+31)) be executed to give the correct answer? If yes, do the operation, showing clearly the steps and result of the computation. If not, explain clearly the reasons why not. (c) Using 2's complement and 6-bit registers, can the operation ((-1) + (-32)) be executed to give the correct answer? If yes, do the operation, showing clearly the steps and result of the computation. If not, explain clearly the reasons why not
