Construct a truth table for the formula ¬P∧ (P → Q). First, I list all the alternatives for P and Q. Next, in the third column, I list the values of ¬P based on the values of P. I use the truth table for negation: When P is true ¬P is false, and when P is false, ¬P is true. 2 WebMathematics normally uses a two-valued logic: every statement is either true or false.
