Then, you may proceed by 0101 ∨ ^ 0010 = 0111. Similarly, to remove bit no. 3, you may proceed by 0101 ∨ ^ 0001 = 0100. This duality comes from the symmetry in the truth table. Note: of course ∨ ^ is here considered the expanded operation on F 2 n, not the digit operation from the answer. – blub law on immigration in united states
