Negate the formula, put the negation in [[disjunctive normal form|06S4WGSEQA]], and use the [[De Morgan laws|0XYVDWGQX2]].\nThe satisfiability problem for formulas in conjunctive normal form with clauses of $3$ literals is NP-complete.\n\n## Explanations\n\n### L1 human\n\nA formula in conjunctive normal form is an and of ors of simple conditions.\nEach clause is a constraint, and the formula is true when all constraints hold.\n",
