Scope (Logic)/Examples/Arbitrary Example 2

Example of Scope in the context of Logic
Consider the statement:
 * $\paren {p \land \paren {q \lor r} } \implies \paren {s \iff \neg \, t}$

We have:
 * $(1): \quad$ The scope of $\land$ is $p$ and $\paren {q \lor r}$.
 * $(2): \quad$ The scope of $\lor$ is $q$ and $r$.
 * $(3): \quad$ The scope of $\implies$ is $\paren {p \land \paren {q \lor r} }$ and $\paren {s \iff \neg \, t}$.
 * $(4): \quad$ The scope of $\iff$ is $s$ and $\neg \, t$.
 * $(5): \quad$ The scope of $\neg$ is $t$.
