Perform the following additions, indicating if the sum exhibits an arithmetic overflow. Assume the numbers are in $8-$bit two's complement form. All binary answers must be in $8-$bit form.

Be careful not to confuse the carry$-$out bit that exceeds the register size with the sign bit that fits within the register size.
