Formal fuzzy logic 7 fuzzy logic can be seen as an extension of ordinary logic, where the main difference is that we use fuzzy sets for the membership of a variable we can have fuzzy propositional logic and fuzzy predicate logic fuzzy logic can have many advantages over ordinary logic in areas like artificial intelligence where a simple truefalse statement is.

Dernoncourt 20 states that fuzzy logic is based on the principle of fuzzy sets by introducing the notion of degree in the verification of a condition, enabling a condition to be in a state other than true or false and provides a very valuable flexibility for reasoning.

Nevertheless, fuzzy logic is a mathematical formalism, and a membership grade is a precise number. Fuzzy logic is a logic or control system of an nvalued logic system which uses the degrees of state degrees of truthof the inputs and produces outputs which depend on the states of the inputs and rate of change of these states rather than the usual true or false 1 or 0, low or high boolean logic binary on which the modern computer is based.
Let x be a set and px be the set of all subsets of x or, equivalently, the set of all functions between x and f0.
