Let's return to the task of translating ordinary statements into symbolic logic. What follows is a dictionary of examples of how common sentences would be
Logic and Mathematical Formulas. We often use logic symbols while writing mathematical statements in a more symbolic way. Example of a Mathematical
We are particularly looking forward to expanding our examples and adding student exercises. Helpful Hints for Translation in Propositional Logic .

For example (e1) Jay and Kay are Sophomores is equivalent to (p1) Jay is a Sophomore andKay is a Sophomore which is symbolized: (s1) J & K Other examples of disguised conjunctions involve relative pronouns (‘who’ ‘which’ ‘that’)
Essential Logic Ronald C Pine Chapter 7: Symbolic Translation Introduction By now you should have an appreciation for the practical nature of formal symbolic analysis In addition to saving a lot of time by being able to see the essence of an argument symbolic analysis is also valuable when arguments and inference situations are
Take Hodges’ second example: after a party a man admits to his wife ‘I did kiss some of the girls’ when in fact he kissed all of them at the party One reaction is to say that he lied: by saying ‘some’ he said ‘not all’ which was false
In many ways frst-order logic formulas are the same way ?p (Person(p) ? ?q (Person(q) ? p? q? Loves(p q) ) )Here's a frst-order logic formula from lecture It objectively has a lot of symbols strewn throughout it ?p (Person(p) ? ?q (Person(q) ? p? q?
By now you should have an appreciation for the practical nature of formal symbolic analysis. In addition to saving a lot of time by being able to see the essence of an argument, symbolic analysis is also valuable when arguments and inference situations are complicated and a way is needed to carefully follow the details of a reasoning trail.
We can also simplify statements in predicate logic using our rules for passing negations over quantifiers, and then applying propositional logical equivalence to the “inside” propositional part. Simplify the statements below (so negation appears only directly next to predicates). ¬?x?y(¬O(x) ? E(y)). ¬?x¬?y¬(x < y ? ?z(x < z ? y < z)).
symbol that we use for the conclusion of an argument. Major connective -- the distinguishing or basic connective of the statement. For instance, for this statement the ( ) is the major connective. the first (~) is the major connective.
Use De Morgan's Laws, and any other logical equivalence facts you know to simplify the following statements. Show all your steps. Your final statements should have negations only appear directly next to the sentence variables or predicates ( P, Q, E(x), etc.), and no double negations.
