Takes hex, internally converts into binary, does the arithmetic, displays results back in hex.

thought it was something like that thanks.

got an exam at 5 and not got any notes etc.

one think though i got an example here, its 5EH - 4CH. the H is upper case but is smaller than other figures and its sort of on the toe of E and C if that makes sense. what does that mean?
