Problem $7$: $(9$ points$)$

Add the following eight$-$bit two's complement numbers together, and then convert all binary quantities into decimal form to verify the accuracy of the addition:

a$)10110111+01110$

Add the following eight$-$bit two's complement numbers together, and then convert all binary

$10000001$l that overflow has occurred in the addition of unsigned binary numbers,

without converting the binary sums to decimal form and having a human being verify the answers?
