3. Multiple-Line Truth Functions
Compound statements in propositional logic are truth functional,
which means that their truth values are determined by the truth
values of their statement components. Because of this truth
functionality, it is possible to compute the truth value of a
compound proposition from a set of initial truth values for the
simple statement components that make up the compound statement,
combined with the truth table definitions of the five propositional
operators.
To compute the truth value...

10. Comparing Statements - Practice 2
Complete the truth table for the given propositions. Indicate
each proposition's main operator by typing a lowercase x in box
beneath the column in which it appears. On the right side of the
truth table, indicate whether each row lists identical or opposite
truth values for the two statements. Also indicate which, if any,
rows show that the statements are consistent with a lowercase x.
Finally, answer the questions beneath the truth table about...
