**Description: **

A **control line M** holds a binary value of either 0 or 1 which determines the operation is carried out whether **addition or subtraction.**

The RESULT will be A-B for signed number, for unsigned number if A>=B.

For unsigned A<B the result will be 2's complement of B-A i.e. , first calculate B+A`+1 and then take 2's complement of the result of B+A`+1.

suppose A=6, B=7 Now , A=110 and B=111 as it is clear that A<B so

B+A`+1=111+001+1

=1000+1

=1001

2's complement of 1001 is (1001)`+1 i.e. , 0110+1=0111
