Question:
Determine which of the following are not well-formed formulas.
1. (S ∙ ∼T) ∨ (U ∙ W)
2. ∼(K ∨ L) ∙ (⊃ G ∨ H)
3. (E ≡ F) ∨ (W ≡ X)
4. (B ⊃ T) ≡ (C ⊃ U )
5. (F ≡ Q) ∙ (A ⊃ E ∨ T)
6. ∼D ∨ [(P ⊃ Q) ∙ (T ⊃ R)]
7. [(D ∙ ∨ Q) ⊃ (P ∨ E)] ∨ [A ⊃ (∙ H)]
8. M(N ⊃ Q) ∨ (C ∙ D)
9. ∼(F ∨ ∼G) ⊃ [(A ≡ E) ∙ ∼H]
