Introduction:
Logic and mathematical reasoning has numerous applications in computer science.
Rules in logic atomic number 18 used in the design of computer circuits, the development of computer programs, the verification of the rightness of programs, and many other ways.
Propositions Basic building blocks of logic. A propose is any many meaningful didactics that is either professedly or false, but not both.
An acceptable proposition is given up the closing value true (or 1).
An unacceptable statement is assign a decision value false (or 0).
Propositional Logic Is the celestial sphere of logic that deals with propositions.
The bases of propositional logic atomic number 18 the three laws of Aristotelian logic.
These are:
1. Law of Identity. A thing Is itself
2. Law of Excluded Middle. A statement is either true or false but not both.
3. Law of Non-Contradiction. No statement is both true and false.
sensible Operators Many mathematical statements are constructed by combining sensation or more propositions. These new propositions are pretended from breathing propositions using logical operators.
The logical operators that are used to form new propositions from two or more existing propositions are called connectives.
? We will use lowercase letters, such as p, q, r, . . . , to constitute propositions.
? The justness value of a true proposition is T or 1. The truth value of a false proposition is F or 0.
Truth table or truth matrix It displays the relationships between the truth values of propositions. An array of decision value ( truth value ).
Logical Operators / Connectives
1. Negation (~ , ¬, !, or not Gate)
The negation of p, denoted by ~p or ¬p, is the proposition not p. (read as not p)If you want to get a adept essay, order it on our website: Orderessay
