In addition to the universal quantifier
WebMar 22, 2024 · So im trying to learn some basic logic and I got stuck on how we use implications with the universal quantifier. However if I've been given a statement of the form ∀ x ∈ A ( x ∈ ∅ → P ( x)) should I read this as ∀ x ( x ∈ A → x ∈ ∅ → P ( x)) or instead ∀ x ( x ∈ A ∧ x ∈ ∅ → P ( x)). Thanks in advance . @mauro ... Suppose it is given that 2·0 = 0 + 0, and 2·1 = 1 + 1, and 2·2 = 2 + 2, etc. This would seem to be a logical conjunction because of the repeated use of "and". However, the "etc." cannot be interpreted as a conjunction in formal logic. Instead, the statement must be rephrased:
