Since a sentence with n logical variables would require a truth table with 2n rows, it is necessary for you to learn more re ned methods of proof. Here are the truth tables of the basic logical connectives.
Albert R Meyer truth-tables.1 . February 14, 2014 . Truth Assignments . A truth assignment assigns a value T or F to each propositional variable. Computer scientists call assignment of values to variables an environment. If we know the environment, we can find the value of a propositional formula. Albert R Meyer . truth-tables.2 .

use truth tables to determine the truth or falsity of a complicated statement based on the truth or falsity of its simple components. Which of the following English statements are ambiguous, and which are propositions?
When you're constructing a truth table, you have to consider all possible assignments of True (T) and False (F) to the component statements. For example, suppose the component statements are P, Q, and R. Each of these statements can be either true or false, so there are possibilities.
