do you know how to find the 1's complement for the numbers? the 2's complement = 1's complement + 1 or you can use the general formula, the nbit 2's complement of a positive integer X, \[X'=2^{n}X\]

i'll do 1 example. +1 in 8bit representation = 0000 0001 1 in 1's complement = 1111 1110 1 in 2's complement = 1111 1111 using the formula, \[X'=2^81\]\[X'=2561=255_{10}=11111111_{2}\]
