pvq: 7 is a prime number or odd

Logic Logic Information derived from the Greek, which is logos, which means word, speech or reason. stainless table So, the logic is the science of correct thinking and reasoning with logic terms There are several terms that will be used in the logic of informatics, namely: The premise: namely a statement argument: the search for the truth of the premise in the form of conclusion stainless table Conclusion: Conclusion
Kata is a series of letters that implies, is a collection of words and phrases that are arranged according to the rules of grammar and implies. In mathematics not all statements are true or false are used in reasoning. The statement also called declarative sentences are sentences that are explained. Also called propositions.
Example: Yogyakarta stainless table is a university town (True). 2 + 2 = 4 (Right).
premise 3: 3 chicken stainless table breed with eggs
Statement: The statement is a sentence that has a value of truth (false / true) statement that does not contain the word circuited sentence, called the primary statement / single / atom. While the statement contains one or more conjunctions sentence, called a compound statement. preposition denoted with lowercase letters p, q, r, s, ... example: p: 13 is an odd number q: soekarno are alumni of UGM r: s poultry chicken is an animal: 2 + 2 = 4
If ...... It so ....... <=>
B
S
If p is the "capital of Semarang, Central Java," then ingkaran or negation of the statement p is ~ p is "not the capital of Semarang, Central Java" or "It is not true that the Central Java capital of Semarang". If p above is true (true), then ingkaran stainless table p (~ p) is worth one (false) and vice versa. Example: a. p: all students have the alma mater ~ p: some students do not have the alma mater
Then p ^ q: Fahmi eating rice and drinking coffee b. p: q slacker Aan child: Aan children ngantukan Then p ^ q: Aan children lazy and ngantukan
pvq: 7 is a prime number or odd
Suppose there are two statements p and q, to show or prove that if p is true will make q is true, too, put the word "IF" before the first statement and then put the word "THEN" before the second statement to obtain a compound statement called " IMPLICATIONS / STATEMENT OF CONDITIONAL / CONDITIONAL stainless table / Hypothetical with the notation "=>".
Notation p Þ q readable: If p then q if pp is a sufficient condition for qq is a necessary condition stainless table for p Example 1. p: Mr. Ali was a pilgrim.
Q: Mr. Ali is a Muslim. p => q: If Mr. Ali is a pilgrim then surely he is a Muslim. 2. P: It's raining. q: Adi bring an umbrella.
