AE

2A

D8,

Try using calculator and switching it to scientific mode.
AE = 174
2A = 42
D8 = 216

As for the actual way to add hex numbers, I cant remember, but im sure google will help

Same way you do it in decimal, Edgar, but it isn't drilled into you like that, so it's no fun. You know that 5 + 3 = 8, because you committed it to memory. You can also do it the 'hard way'. Five anna 1 is 6 anna 1 is 7 anna 1 is 8. Same with hex. E + A = 8, carry the 1. If you convert beforehand you have to convert back, which is a pain. So is doing it in the hard way: E anna 1 = F anna 1 = 0 (carry the 1, 10) anna 2 = 11 .... blah blah, BS. For me, the best thing to do is just memorize the stuff and go with it. Since you don't have to live with it on a daily basis before the invention of such calculators, you probably just wanna go that route.
