Disjunctive Normal Form: Also defined as

When presenting disjunctive normal form, some sources include parentheses as appropriate within both the conjunctions and disjunctions in a standard format, for example:

$\paren {\paren {\paren {\neg p \land q} \land r} \lor \paren {\neg q \land r} } \lor \paren {\neg r}$

but this is usually considered unnecessary in light of the Rule of Distribution.
