In addition to the universal quantifier

WebNote that, in addition to the new rules for reasoning with quantifiers, you will still have to use techniques like conditional derivation (when proving a conditional) and indirect derivation (when proving something that is not a conditional, and for which you cannot find a direct derivation). These will require universal instantiation. 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:

WebUniversal quantification. . In mathematical logic, a universal quantification is a type of quantifier, a logical constant which is interpreted as " given any ", " for all ", or " for any ". It expresses that a predicate can be satisfied by every member of a domain of discourse. In other words, it is the predication of a property or relation to ...
