Introduction to Logic Structures


Logic is the study of the principles and methods that distinguish between a valid and an invalid argument.
Statement is a declarative sentence that is either true (T) or false (F) but not both. A statement is also referred to as a proposition.

If a proposition is true, we say that it has a truth value of "True". If a proposition is false, its truth value is "falseQuot. The truth values "true" and "false" are, respectively, denoted by the letters T and F.

AND, OR, NOT are called Logical Connectives.

Statements are symbolically represented by letters such as P, p, q, r, s, T, . . .
