hi all,

assume: negative integer is represented in digital computer
        as 2 complement and assume 4 bits computer

 so  -3 looks like:  1101 
             and     1101 = 13 as a positive number (forget the sign bit)
                     13 = 16 - 3

so in general if we have n-bits computer, a negative integer number
b in 2 complement is 2**n + b (in postive representation).

the above statement is intuitively true.
Comment anyone ???.
