Obviosuly I don't know.
Then how about doing what I have suggested twice, and looking up hexadecimal?

Do I have to learn whole tabele or?
Yeah, you do. I realize that learning six digits more than the ten you (hopefully) already know is an unfair expectation -- but life isn't always fair.

Things to understand:
1. You should get the same answer regardless of the number base that you use.
2. You need to make yourself a hexadeximal addition table with 16 rows and 16 columns
3. Verify that you get the same answer in decimal, hexadecimal, and binary.
4. If steps 1-3 fail, then a switch to Art History is recommended.

I know what that is, I just didn't know that I have to learn whole tabele by hard. I thought there is some simple way to write a,b,c haha

Note that they do not sum to 0x8, is what I should have said
0xD added to 0xB is 0x18. And that's the first column.

You clearly do NOT know what hexadecimal is if you can't figure out what 'b' and 'd' are. So go learn it. It should take just a few minutes (less than two, being generous) to be able to know how to write all sixteen hexadecimal digits without referring to any reference whatsoever.

Ok. A is 10, B is 11 and so on...
But how i know how much DD or FB?

How can I know which adress is A and B? Why did you choose 0004?
Assuming an 8-bit processor, the Move instruction using immediate data requires two bytes. One for the instruction and the next one for the data to be moved.

Do you have a scientific calculator that does hex math? Your computer probably does. Or you can find it on the Internet.
Or just add it in binary by hand, one bit at a time..

Given the decimial digits 0 through 9, how do you know how much 42 is?

It's the same thing.

I give up. I'm exercising the self locking feature of this thread and turning on the ignore bit as well.

Okay, guys I understand how to get binarty numbers. I add them. I get CVZS flags, what now?

Which processor and/or assembly language are you talking about? The format and behavior of the MOV or ADD command depends on which assembler is being used.

That's been suggested three (or more) times already. He doesn't appear interested or willing to look up and read anything on his own.
In what language?
English can be tough. "Engineering English" can be tougher.

I suggested that he Google hexadecimal. He can do that in whatever language best suits his abilities.
