Do the following operations on the 6 bit two\'s complement numbers, indicate if overflow has occurred or not occurred.

Solution

[1] 101111
+ 101101
---------
   1011100   --> Overfolw Occurred
  
[2] 101010  
- 100101
-----------
    000101   --> NO overflow

[3] 010101
+ 101110
-----------
   1000011 --> OVERFOLW
  
[4] 110101  
- 100110
----------
    001111 --> NO OVERFLOW

[5] 001101 (13)
-   010011 (19)
------------
      0110 (-6) --> if not UN binnary number --> NO OVERFLOW
                  if unsigned binary binnary number --> OVERFLOW
     
     
[6] 101011
+ 100010
-----------
   1001101 --> Overflow

[7] 111001
- 011001
--------
    100000 --> no overflow

[8] 010111
+ 011101
----------
    110100 --> NO overflow
