Let A be a three-bit unsigned number. Use a seven-bit adder (and NOT gates, as necessary) to design a circuit that calculates the following operations. Note that the output may be assumed as unsigned, unless it is possible for the operation to produce a negative answer, in which case, the output must be correct in 2’s complement:
W = 3A + 1
X = 2A – 17
Y = 40A + 6
Z = 32 – 4A
