Using the distributivity law for propositional logic
Notice that, por instance, p ∨ q p ∨ q is a statement itself, so you can apply the rule just as you did. You’re right: the underlying law is the same as in ordinary algebra, so the calculation works out in the same fashion. In detail: Think of p ∨ q p ∨ q as a …
Distributive law in logic - Mathematics Stack Exchange
2015年9月17日 · EDIT: There are two Distributive laws: $$(p \lor (q \land r) \equiv (p \lor q) \land (p \lor r)$$ and $$(p \land (q \lor r) \equiv (p \land q) \lor (p \land r).$$ So we'll have $$(\neg p \land q) \lor ( \neg p \land \neg q)$$

Distributive property - Wikipedia
In mathematics, the distributive property of binary operations is a generalization of the distributive law, which asserts that the equality (+) = + is always true in elementary algebra.

Distributive modulo? - Mathematics Stack Exchange
The OP seems to be using modulo as an operator; and that operator is NOT distributive. If we let $\%$ be the the 'modulus' operator (as it is usually denoted in computer languages) then $$(2 + 2) \% 3 = 1 \neq (2 \%3) + (2 \% 3) = 2 + 2 = 4$$ In mathematical discourse, modulus is …
2.5: Logical Equivalences - Mathematics LibreTexts
2021年7月7日 · Distributive laws: When we mix two different operations on three logical statements, one of them has to work on a pair of statements first, forming an “inner” operation. This is followed by the “outer” operation to complete the compound statement. Distributive laws say that we can distribute the “outer” operation over the inner one.

2024年10月28日 · Math 1310-Technical Math for IT Unit 4 -page 1 Unit #4 -Boolean Algebra Boolean algebra was first introduced by George Boole in his book, The Mathematical Analysis of Logic in 1847. Variables in a Boolean algebra take on values that are not numbers but logical values: TRUE or FALSE, sometimes represented by 1 (for TRUE) and 0 (for FALSE). Switching Circuits Boolean algebra was first applied to ...
Distributive property - Art of Problem Solving
Distributive property Given two binary operations and acting on a set , we say that has the distributive property over (or distributes over ) if, for all we have and . Note that if the operation is commutative , these two conditions are the same, but if does not commute then we could have operations which left-distribute but do not right ...
Distributive property - Wikipedia - BME
In abstract algebra and formal logic, the distributive property of binary operations generalizes the distributive law from Boolean algebra and elementary algebra. In propositional logic, distribution refers to two valid rules of replacement. The rules allow one to reformulate conjunctions and disjunctions within logical proofs. For example, in ...
