Final answer:
To perform binary addition, add the corresponding bits in the two numbers. Overflow occurs when the sum requires more bits than the original representation.
Step-by-step explanation:
To perform binary addition, you simply add the corresponding bits in the two binary numbers, starting from the rightmost bit. If the sum of two bits is 2 or greater, a carry is generated to the next bit. Overflow occurs when the sum requires more bits than the original number representation has.
a. 1010 + 0110 = 10000. There is overflow because the sum requires an additional bit.
b. 1111 + 0111 = 10110. There is no overflow.
c. 1001 + 0101 = 1110. There is no overflow.
d. 1100 + 0110 = 10010. There is overflow.
e. 0100 + 0100 = 1000. There is no overflow.
