Predicates & Quantifiers Part 02

Quantifiers:

Quantifiers tell us how much of a domain (the set of all possible values for the variable) the predicate applies to.
There are two main quantifiers:
Universal quantifier (∀): This means "for all." It's written as a capital "A" followed by a variable and a colon (∀x:). It indicates that the predicate is true for every element in the domain.
Existential quantifier (∃): This means "there exists." Written as an upside-down "E" with a variable and colon (∃x:), it indicates that the predicate is true for at least one element in the domain.
