"WebAdd a comment. 3. You are confusing operations on a single bit with operations on a byte,or word. (Multiple bits) A single bit represents either 0 or 1 depending on its value. If you add two bits, and ignore the carry, you are adding "mod2". 0+0 = 0 0+1 = 1 1+0 = 1 1+1 overflows, or carries, and you have 0. this is exactly the same as XOR. " - Bit by bit xor
