A little confused on this problem... Suppose I have
000111
+ 111101
_________
wouldn't I just have
7 - 61 = -68
Thus my answer would be: 1000100 ? But wouldn't I have an overflow? & if i Had an overflow and discarded that 1 then wouldn;t I have the incorrect answer? OR do I need to take the second number and invert it and then add 1? But wouldn't doing that change the number all together?
