edited Oct 7, 2010 at 1:53Using two's complement to represent negative values has the benefit that subtraction and addition are the same. In your case, you can think of 12 - 7 as 12 + (-7). Hence you only need to find the two's complement representation of -7 and add it to +12:
12 001100-7 111001 -- to get this, invert all bits of 7 (000111) and add 1----------5 1000101Then discard the carry (indicates overflow), and you have your result: 000101 which equals to 5 as expected.
For your example of -15 + 2, simply follow the same procedure to get the two's complement repr...
