Semantics of propositional logic The meaning of a formula depends on: • The meaning of the propositional atoms (that occur in that formula) a declarative sentence is either true or false captured as an assignment of truth values (B = {T,F}) to the propositional atoms: a valuation v: P→ B

Such combinations allow you to describe situations, and what properties these situations have or lack: some-thing is ‘not this, but that’.

It is important to remember that propositional logic does not really care about the content of the statements.

That way, the proposition All cats are dogs and the earth is a disc is made of two propositions, All cats are dogs, and The Earth is a disc. These are joined together with the logical connective AND. Se hela listan på stat.berkeley.edu Let p and q be two propositions. Consider the following two formulae in propositional logic. S1: ( eg p\wedge(p\vee q))\rightarrow q S2: q\rightarrow( eg p\wedge(p\vee q)) Which one of the following choices is correct? Propositional logic studies the ways statements can interact with each other. It is important to remember that propositional logic does not really care about the content of the statements. For example, in terms of propositional logic, the claims, “if the moon is made of cheese then basketballs are round,” and “if spiders have eight legs then Sam walks with a limp” are exactly the same.
