Truth table of Negation

Statement of negation is a statement which denied earlier statements, or opponents of the preliminary statement. To make the truth table of the negation statement, first we create the truth table for the truth value of statements of origin. The statement of origin (p) can be valuable right or wrong. So the truth value table of the statement p is:

p
B
S

If p is true, then ~ p would be worth one, because ~ p deny the truth of p. If p is wrong, ~ p is true. Truth table for negation describe the truth value given by ~ p. The first line in the truth table read "~ p false when p is true", while the second line read "~ p is true when p is wrong."

p~p
BS
S B
