work $($no calculators except to check your answer$).$ Assume all values are $8-$bit signed binary in $S2C$ form. Present the $8$bit result $($in hex$)$ and list the $N_{,}{Z}_{,}{C}_{?},$ and $V$ flag values for each problem.

You must show your work, in binary, because you cannot determine flags without seeing the binary values and results. Feel free to use a calculator $($in programmer$/$binary mode, set to byte size$)$ to check your work each step, but try to do each step manually first for practice.
