The elimination rule for the logical constant tells what other truths we can deduce from the truth of a conjunction, disjunction, etc. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. For one, the natural deduction system also has no branching rules. More importantly though, within a natural deduction system, we must frequently make sub-derivations; there is no parallel for this in the other system.

Natural deduction rules come in various forms, where one either uses formulas A, or sequents ‘A(where is a sequence or a nite set of formulas). Other formalisms use a linear format, using ags or boxes to explicitly manage the open and discharged assumptions.

For the biconditional you may use any of the symbols: ↔ ≡ <-> <> (or in TFL only: =) I am familiar with the main rules of natural deduction: $∧i, ∧e1, ¬¬e, ⇒e, ⇒i, ∨i, ∨e$ (slightly). However, when presented with the following premise: $$\sim a ∧ (a ∨ b)$$ I used $∧ e$ to obtain: $$\sim a , (a ∨ b)$$ Now I am stuck on what exact 'rule' to apply here.
