Disjunction
From HandWiki
The logical operation of formation of the statement "A or B" from two statements $A$ and $B$. In formalized languages the disjunction of two statements $A$ and $B$ is denoted by $A\lor B$. The statements $A$ and $B$ are called the disjunctive terms of the statement $A\lor B$. The meaning of the disjunction can be expressed by the following truth table:
| $A$ | $B$ | $A\lor B$ |
| $T$ | $T$ | $T$ |
| $T$ | $F$ | $T$ |
| $F$ | $T$ | $T$ |
| $F$ | $F$ | $F$ |
