Using quantifiers to create such propositions is called quantification. There are two types of quantification-. 1. Universal Quantification- Mathematical statements sometimes assert that a property is true for all the values of a variable in a particular …
Quantifiers We need quantifiers to express the meaning of English words including all and some: “All men are Mortal.” “Some cats do not have fur.” The two most important quantifiers are: Universal Quantifier , “For all,” symbol: ∀ Existential Quantifier, “There exists,” symbol: ∃ We write as in ∀x P (x) and ∃x P (x).

CQ Translations Let the domain contain the set of all students and courses. Define the following predicates: S(x): x is a student. C(y): y is a course. T(x,y): student x has taken course y. Translate the sentence “every student has taken some course.” into a predicate formula. Let x refer to a student and let y refer to a course.

We can express these two things using predicates. ... pass the midterm” can be translated as \forall x P(x) where the domain of x is people in this class.
Predicate Logic: Multiply General Monadic. When do you need more than one quantifier? The answer is not simple. You will not err if, in translating compound statements, you add a new quantifier for every component which would need a quantifier if you were to translate it as an entire statement unto itself.
