| 2. | Thus whenever a theorem and its reciprocal are true we have a biconditional.
|
| 3. | "' Biconditional elimination "'is the name of two biconditional.

| 4. | "' Biconditional elimination "'is the name of two biconditional.
|
| 5. | The plain English " if'" may sometimes be used as a biconditional.
|
| 6. | Except for negation and biconditional, its truth tables are all different from the above.
|
| 7. | The negation of XOR is logical biconditional, which outputs true only when both inputs are the same.
|
| 8. | These unexpected truths arise because speakers of English ( and other natural languages ) are tempted to material biconditional.
|
| 9. | In that case, in the conditional, the result is true, yet in the biconditional the result is false.
|
| 10. | Intuitively, the right side of the biconditional says that A's failing to hold necessarily ( or strictly ) implies a sanction.
