Subtraction using 1’s and 2’s complement

Using 1’s complement

     

     

      remove the extra bit and add on its remaining bit.

     find its 1’s complement of result in step 2 and add (-)ve sign

Using 2’s complement

     

     

      remove the extra bit.

     find its 2’s complement of result in step 2 and add (-)ve sign

 

1’s complement

Example 1

X =  1010  

Y =  101  

 

Step 1

Y =  0101

1’s comp of Y = 1010

 

Step 2

      1010

+   1010

    ---------

  1 0100   ← The leftmost `1` is the carry out

 

Step 3

 0100

+     1

---------

  0101   = +5 (correct)

 

Therefore, 1010   -  101=101

 

Example 2

X = 101

Y = 1010

 

Step 1

Y = 1010 → 1’s comp = 0101

 

Step 2

      0101

+    0101

     ---------

     1010   ← no carry out

 

Step 3

1’s comp of 1010 = 0101 →-0101

 

Therefore, 101   -  1010=-101

 

2’s complement

Example 3

X = 111

Y =101

 

step 1

1’s complement of Y → 010

add 1 → 011(2’s complement )

 

Step 2

       111 

+     011

     ---------

      1010      

step 3 à The leftmost `1` is the carry out remove it

Therefore, 111   -  101=10

 

Example 4

X = 101

Y =111

 

Step 1

1’s complement of Y → 000

add 1 → 001(2’s complement )

 

Step 2

       101 

+     001

     ---------

      110       

 

Step 3

2’s complement of step 2 answer →-010

Therefore, 101   -  111=-10
