Hi Guys,

Can somone help me with this please.

1. Unsigned/Signed Binary Operations

(a) Perform the following 8-bit unsigned operations, and in each
case determine the value of the C bit. Determine whether the operation is valid or invalid to 8 bits in

All working must be shown and note that the value of Cout must
also be shown.

i. %0101 0011 + %0111 1111
ii. %1000 0111 + %1100 1110
iii. %1000 0001 - %1100 0000
iv. %1010 1011 - %1100 1100

(b) Perform the operations above again, if necessary, as 8-bit
signed operations and in each case determine the value of the V
bit.

Determine whether the operation is valid or invalid to 8 bits in
each case. State your reasons. All working must be shown and
note that values of Cin and Cout must also be shown.

I'm trying to learn but dont knwo where to start.

Thanks Guys
