How To Calculate Memory Address ( Flat , Segmented )

Hello
Can anyone learn me how to compute the address size of flat & segmented memory address

or

16 blocks each block size 32 K locations =

Thanks i appreciated any help ;)

Actually, I'm not quite sure whether I really understand your question, but to me it sounds like what you're looking for is really basic math. Or is that about the x86 segmented addressing scheme? (From the math POV this isn't really advanced either, though...)
