Please help me solve these questions.

Perform the following additions in four bit binary representation. Write out your work in binary. At the conclusion of each, give the status of the following flags: Zero, Sign, Carry, Overflow. -7 + 2 -4 + 4 3 + 4 5 + 4 5 + 3 3 + -3 4 + 0 7 + 6 Perform the following subtractions in four bit binary representation. Do this by complementing the subtrahend and adding that to the minuend. Write out your work in binary. (That is, instead of "5 - 3" perform "5 + (-3)".) At the conclusion of each, give the status of the following flags: Zero, Sign, Carry, Overflow. 2 - 7 5 - 2 7 - 7 6 - 6 1 - 6 5 - 4 0 - 4 -7 - 6 Perform the following additions in eight bit binary representation.
