Determine whether each statement is true of false (you do not need truth tables to make the determination!) If 3 is a negative number, then 5 > 7. If 5 > 3, then 2 + 7 = 4. If Richmond is the capital of North Carolina, then Raleigh is the capital of New York. If Tuesday follows Monday, then April follows March. If 4 > 3, then 2 + 5 = 6.

A truth table gives the truth value of a compound statement for all possible truth values of the simple statements that make it up. We will consider the truth tables for negation, the conjunction, the disjunction, and the conditional.

The equivalences that are less obvious can be shown to be true using truth tables. Example 3. Show the first distributive law is valid. One way is simply to make the truth table; see right. Note that both p(q + r) and pq + pr are true precisely in the last three rows. However, we can save ourselves some work if we argue as follows.

A truth table for this situation would look like this: ... Lewis Carroll, author of Alice’s Adventures in Wonderland, was a math and logic teacher, and wrote two books on logic. In them, he would propose premises as a puzzle, to be connected using syllogisms. The following example is one such puzzle.

3. If there is a row in the truth table where every premise column is true but the conclusion column is false (a bad row) then the argument is . invalid. If there are no bad rows, then the argument is valid. EXAMPLE 2.1.1. Use a truth table to test the validity of the following argument. If the apartment is damaged, then the deposit won't be ...

A truth table is a device that allows us to analyze and compare compound logic statements. Consider the symbolic statement p ( ~q. Whether this statement is true or false depends upon whether its variable parts are true or false, as well as on the behavior of the “or” connective and the “negation” operator.

A truth table shows all possible truth values. Tautologies: In logic, a tautology is a compound sentence that is always true, no matter what truth values are assigned to the simple sentences within the compound sentence. For example, let us study the truth value of (p Λ q) → (p V q) by building a truth table. p q p Λ q p V q (p Λ q) → (p ...
