. Assume all the values are in 8-bit 2s complement representation. Perform the following operations
. i. 01111111 + 11111111
ii. 00100101 - 10110111
ans i :
(01111111)2 = (127)10
(11111111)2 = (-1)10 (Taking 2s complement and attaching a negative sign.)
(127)10 + (-1)10 = 127 - 1 = (126)10
(126)10 = (01111110)2
So the answer is 01111110.
ans ii :
(00100101)2 = (37)10
(10110111)2 = (-73)10 (Taking 2s complement and attaching a negative sign.)
(37)10 - (-73)10 = 37 - (-73) = 37 + 73 = (110)10
(110)10 = (01101110)2
So the answer is 01101110.

Q.50 Please solve all of them to get a great review. Perform the following 8-bit operations assuming that the numbers are encoded in 2's complement form and report the sum. Also report which ones, if any, result in overflow. Remember that subtraction can be thought of as "adding the negative" of the argument.
