Document Summary
Simple statement: contains no other statement as a component part (represented as a letter) Complex statement: contains at least one other statement as a component part. Logical operator/connective- special expressions that combine simple into complex. A & j- false if at least one letter is false. A v j- false if both letters are false. Spotting logical operators: conjunctions: but, even though, however, although, moreover, nonetheless, negations: it is not true that, disjunctions: in logic, inclusive ie. a or b or both. Unless - or: conditionals: a means/implies b, whenever a, b. Operators are truth-functional connectives - a f(x) from truth values of 2 simple to truth values of complex. If by itself introduces antecedent, no matter where it occurs in the statement. If i skip class, i"ll fail and i"ll fail if i skip class are both skip fail.
