10. For any doubleword size number x,
100000000 - x
= (100000000 - 1) - x + 1
= (FFFFFFFF - x) + 1
FFFFFFFF is a pattern of 32 1s. Subtracting 0 from 1 gives 1 and subtracting 1 from 1
gives 0, that is, subtracting any bit from 1 "flips" the bit. Subtracting x from FFFFFFFF
does this for each of the 32 bits. Therefore subtracting the hex number from
100000000 is equivalent to taking the 1s complement and then adding 1.
Other sizes work similarly.
