Integer. Perform the following calculations.

a$)(01101111)2$C $+(00110110)2$C $=(10100101)2$C

Is there an overflow? Please explain.

No because the sum is within the range for $8-$bit $2$ complement

numbers

b$)(01001001)2(00101111)2=(10011010)2,$ assuming $8-$bit

system and unsigned binary number
