3. Ingkaran (negation), which is a new statement that is constructed so that the original statement dish drainers is true if one of the original statement if the statement is false and completely original (denoted with ~)
Sometimes, we are required to negate or make a new statement which indicates that there is a denial of the statement, using assembler "not" or "no". In addition, they have to combine two or more statements using assembler "or", "and", "if ... then", and "if and only if ..." known in mathematics as a conjunction, dish drainers disjunction, implication , and biimplikasi. Conjunctions sentence also known as assemblers or coupling with the above operations. This section will discuss the assembler-fabricators
From these examples it is clear that p is a statement that is true for Surabaya in fact it is the capital of East Java, so that the feed is false. dish drainers However, if p is false then p will be true as indicated by the truth table below.
Adi statement is true and which is false in terms of the following four cases, namely: (1) Fahmi indeed eat rice and he also drank coffee, (2) Fahmi eat rice, but he did not drink coffee, (3) Fahmi not eat rice but he drank coffee, and (4) Fahmi not eat rice and he does not drink coffee .:
In the first case, Fahmi indeed eat rice and he also drank coffee. In such cases it is not possible Adi earlier statement is false. The reason, Adi statement earlier in accordance with reality. dish drainers In the second case, Fahmi eat rice but it was not minu coffee. In this case of course Adi earlier statement is false because although Fahmi had to eat rice, but he did not drink coffee as stated Adi. Accordingly, in the third case, Fahmi not eat rice even though he had a cup of coffee. As the two earlier cases, the statement is false that Adi had fahmi not eat rice as stated Adi that Fahmi eating rice and drinking coffee. Finally in the fourth case, Fahmi not eat rice and do not drink coffee. In this case; Adi compound statement dish drainers is false because there is no conformity between the declared with actual reality.
Based on the above, it can be concluded that a conjunction p q will be true only if the components, ie both p and q, both are true, while the value of truth that otherwise it would be worth one as shown in the following truth table:
S
Disjunction is a compound statement that using assembler dish drainers "or". For example, Adi following statement: "Fahmi eat rice or coffee." Adi statement in the following dish drainers four cases, namely: (1) Fahmi indeed eat rice and he also drank coffee, (2) Fahmi eat rice, but he did not drink coffee, (3) Fahmi not eat rice, but he drank coffee, and (4) Fahmi not eat bread and he did not drink coffee.
In the first case, Fahmi indeed eat rice and he also drank coffee. In such cases, it is not possible Adi statement is false, because the statement was in accordance with the reality Adi. In the second case, Fahmi eat rice, but he did not drink coffee. In this case, of course, the statement is true because earlier Adi Fahmi is correct eating rice, though she does not drink coffee as stated Adi. While in the third case, Fahmi not eat rice, but he drank coffee. As the second case above, a compound statement earlier Adi Fahmi is true because although not eat rice, but he had a cup of coffee as stated Adi. Finally in the fourth case, Fahmi not eat bread and he did not drink coffee. In this case the compound statement Adi earlier statement is false because there is no conformity between the declared with actual reality. He stated Fahmi eat rice or coffee but in reality, Fahmi did not do that.
Based on the above, dish drainers it can be concluded that a disjunction p U q will be valuable only if one of its components, dish drainers namely both p and q, both are worth one, which otherwise it will be true as shown in the following truth table:
B
Suppose there are two statements p and q. Which often menja
