Q. Show the procedure twos complement subtraction?
Two's complement subtraction is the binary addition of the minuend to the 2's complement of the subtrahend (adding a negative number is the same as subtracting a positive one).
For example,
7 - 12 = (-5)
0000 0111 = +7
+ 1111 0100 = -12
--------------------------------------------------------------------------------
1111 1011 = -5
