WebHere are some more equations of subtraction using bitwise operators by srlabib! As : a-b = a-(a&b)-x. Here a-(a&b) and (a⊕(a&b)) are actually the same! and x = (a b)⊕a. So now it is clear that. a-b = (a⊕(a&b)) — ((a b)⊕a) Now. a⊕(a&b) = (a b)⊕b. b⊕(a&b) = (a b)⊕a. Using these two properties we can build four equations!

Case 2: One of A and B ends in 1 and the other ends in 0. Assume, without loss of generality, that A ends in 1 and B ends in 0. Then A & X + B & X = 0 + X = X, so either choice of bit for the last bit of X works.
