Pedantically and ignoring the RAID aspect, just looking at the equations scientifically, I would say that only the first one is wrong as (64K / 4K) = 16, not 16K. It should be expressed as (64 / 4)K = 16K. The other two lines do read correctly but, in the spirit of conformity, I would suggest (3 * 16)K = 48K and (16 + 16)K = 32K, respectively. Perhaps the original author would care to comment and adjust where necessary? Alan.
