WebIn first order logic this can be written as ∀n(prime(n) → n > 1). The reason is that the original statement is equivalent to the statement “for every natural number, if it is prime, then it is greater than 1”. Similarly, suppose we want to say “there exists a … WebNotice how the ∨E step is an instance of the rule as abstractly stated in Figure 3.6.2. The disjunction A ∨ B referred to in the rule is q ∨ r in this instance, and the set X is {p, p → (q ∨ r)}. Y is the empty set, and Z is {q → r}. In the conclusion of the rule, C is r, and the set of assumptions is X ∪ Y ∪ Z which is {p → ...
