Question

What is represented by p v q?

Answer 1

$\lor$ is the logical or/disjunction symbol. $p\lor q$ means "$p$ or $q$". Disjunction is commutative, which means $p\lor q$ is equivalent to $q\lor p$.

So if $p$ represents $x$ and $q$ represents $x>3$, then $p\lor q\equiv q\lor p$ means $x>3$ or $x$.
