a AND gate, b OR gate, c INV gate, d NAND gate, e NOR gate. Each gate with an even number of inputs requires a third biasing value to implement its function and eliminate neutrality. The + sign indicates that the input solutions are mixed. The crossing output lines indicate that an inversion has been performed.
