What is logical equivalence?
Logical equivalence is a type of relationship between two statements or sentences in propositional logic or Boolean algebra. You can’t get very far in logic without talking about propositional logic also known as propositional calculus. A proposition is a declarative sentence (a sentence that declares a fact) that is either true or false.

What is discrete logarithm calculator?
Discrete logarithm calculator. The discrete logarithm problem is to find the exponent in the expression Base Exponent = Power (mod Modulus). This applet works for both prime and composite moduli. The only restriction is that the base and the modulus, and the power and the modulus must be relatively prime.
How do you calculate logical equivalence?
To test for logical equivalence of 2 statements, construct a truth table that includes every variable to be evaluated, and then check to see if the resulting truth values of the 2 statements are equivalent.
Is there a logic calculator?
The Logic Calculator is a free app on the iOS (iPhones and iPads), Android (phones, tablets, etc.) and Windows (desktops, laptops, tablets, xbox ones) platforms. I coded it to allow users of propositional logic to perform operations with the same ease as that offered by a mathematical calculator.
What is equivalences in discrete mathematics?
Two propositions p and q are logically equivalent if their truth tables are the same. Namely, p and q are logically equivalent if p ↔ q is a tautology. If p and q are logically equivalent, we write p ≡ q.

What is logically equivalent to P → Q?
The propositions are equal or logically equivalent if they always have the same truth value. That is, p and q are logically equivalent if p is true whenever q is true, and vice versa, and if p is false whenever q is false, and vice versa. If p and q are logically equivalent, we write p = q.
What does V mean in logic?
orIn symbolic logic, a sign such as V connects two statements to form a third statement. For example, V replaces the word “or” and Λ replaces the word “and.” The following is a list of the symbols commonly encountered: p, q, r,…
Are P → q and P ∨ q logically equivalent?
P→Q is logically equivalent to ⌝P∨Q. So. ⌝(P→Q) is logically equivalent to ⌝(⌝P∨Q). Hence, by one of De Morgan’s Laws (Theorem 2.5), ⌝(P→Q) is logically equivalent to ⌝(⌝P)∧⌝Q.
Are the statements P → q ∨ R and P → q ∨ P → are logically equivalent?
Since columns corresponding to p∨(q∧r) and (p∨q)∧(p∨r) match, the propositions are logically equivalent. This particular equivalence is known as the Distributive Law.
What does P → q mean?
The implication p → q (read: p implies q, or if p then q) is the state- ment which asserts that if p is true, then q is also true. We agree that p → q is true when p is false. The statement p is called the hypothesis of the implication, and the statement q is called the conclusion of the implication.

How do you know if you are a Tautologist?
If you are given any statement or argument, you can determine if it is a tautology by constructing a truth table for the statement and looking at the final column in the truth table. If all of the truth values in the final column are true, then the statement is a tautology.
