Hi, I'm trying to add two hexadecimal numbers, FE20 and 0A3F. I thought I should be getting a group of 4 hexadecimal numbers in my answer (this is out of the Computer Systems 4th Edition textbook by Warford). I've attached an image of the problem. I'm working on 6e and the computer system this book works with is Pep/8. Now the answer I get is 085F with a carry of 1 on the end but I feel like I read somewhere that you have to do something with that carry bit such as bringing it back down and adding it to the sum previously achieved. I don't know if I'm right or if I need to do something else but I hope someone can help me.
