Operadores lógicos
| Operador | Símbolo | Lenguaje natural | Puerta |
|---|---|---|---|
| Negación | ¬ | no | NOT |
| Conjunción | ∧ | y | AND |
| Disyunción | ∨ | o | OR |
| Disyunción exclusiva | ⊕ | o bien... o bien | XOR |
| Conjunción opuesta | ↑ | no... y | NAND |
| Disyunción opuesta | ↓ | ni... ni | NOR |
| Bicondicional | ↔ | si y sólo si | XNOR |
| Condicional | → | si... entonces | NOT + AND |
PISTA: para recordar el símbolo ∧ podemos pensar que se parece a la A de And (y).
