Addition in signed magnitude system in Computer Science?

This is exactly how you do addition by hand: If the signs are the same, add the mangitudes; is they differ, check which one has larger magnitude (that is the sign of the result), and substract the smaller magnitude from the larger.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
