One additional thought to the two's complement is this: If you think of a number line, every positive integer has a negative. But, zero has no negative, there is only zero. If you complement zero, it would be all xffffs for zero, but since there is no negative zero, adding a one gets zero back to what it should be, x0000s. (and all other negative values are adjusted as well)
