The expression ( p \land q ) is called the "conjunction" of statements ( p ) and ( q ). It is true only when both ( p ) and ( q ) are true; otherwise, it is false. In logical terms, conjunction represents the logical AND operation.
A biconditional statement, expressed as "P if and only if Q" (P ↔ Q), can be rewritten as two conditional statements: "If P, then Q" (P → Q) and "If Q, then P" (Q → P). This means that both conditions must be true for the biconditional to hold. Essentially, the biconditional asserts that P and Q are equivalent in truth value.
The negation of a conditional statement is called the "inverse." In formal logic, if the original conditional statement is "If P, then Q" (P → Q), its negation is expressed as "It is not the case that if P, then Q," which can be more specifically represented as "P and not Q" (P ∧ ¬Q). This means that P is true while Q is false, which contradicts the original implication.
In logic, "p" and "q" are commonly used symbols to represent propositions or statements that can be either true or false. They serve as variables in logical expressions and are often used in conjunction with logical operators like "and," "or," and "not" to form more complex statements. For example, in the expression "p and q," both propositions need to be true for the overall statement to be true.
If ( pq ) and ( qr ) are both true statements, then it follows that both ( p ) and ( q ) must be true (since ( pq ) is true) and both ( q ) and ( r ) must be true (since ( qr ) is true). Consequently, this implies that ( q ) is true in both cases. However, we cannot definitively conclude the truth values of ( p ) or ( r ) without additional information. Thus, the statements themselves do not inherently guarantee the truth of ( p ) or ( r ) alone.

there are 32 types of thesis statements possible
There is big deal. x and y are commonly used as variables, p and q are used a statements in logic.
Then p/q is a rational number.
The negation of a conditional statement is called the "inverse." In formal logic, if the original conditional statement is "If P, then Q" (P → Q), its negation is expressed as "It is not the case that if P, then Q," which can be more specifically represented as "P and not Q" (P ∧ ¬Q). This means that P is true while Q is false, which contradicts the original implication.
Let us consider "This statement is false." This quotation could also be read as "This, which is a statement, is false," which could by extent be read as "This is a statement and it is false." Let's call this quotation P. The statement that P is a statement will be called Q. If S, then R and S equals R; therefore, if Q, then P equals not-P (since it equals Q and not-P). Since P cannot equal not-P, we know that Q is false. Since Q is false, P is not a statement. Since P says that it is a statement, which is false, P itself is false. Note that being false does not make P a statement; all things that are statements are true or false, but it is not necessarily true that all things that are true or false are statements. In summary: "this statement is false" is false because it says it's a statement but it isn't.
It is an if and only if (often shortened to iff) is usually written as p <=> q. This is also known as Equivalence. If you have a conditional p => q and it's converse q => p we can then connect them with an & we have: p => q & q => p. So, in essence, Equivalence is just a shortened version of p => q & q => p .
Converse: If p r then p q and q rContrapositive: If not p r then not (p q and q r) = If not p r then not p q or not q r Inverse: If not p q and q r then not p r = If not p q or not q r then not p r
The sum of p and q means (p+q). The difference of p and q means (p-q).
q + p
Not sure I can do a table here but: P True, Q True then P -> Q True P True, Q False then P -> Q False P False, Q True then P -> Q True P False, Q False then P -> Q True It is the same as not(P) OR Q
