CONTRAPOSITIVE Meaning and
Definition
-
Contrapositive is a term used in logic and mathematics to describe the relationship between two statements. It refers to a logical inference or proposition that is formed by negating and interchanging the terms of the original statement.
In a contrapositive statement, the subject and the predicate of the original proposition are switched, and both are negated. This means that if the original statement is "If P, then Q," the contrapositive would be "If not Q, then not P."
This concept is based on the principle of logical equivalence, which states that a statement and its contrapositive will always have the same truth value. In other words, if the original statement is true, its contrapositive will also be true, and if the original statement is false, its contrapositive will also be false. This principle is a fundamental part of deductive reasoning and is often used to prove the validity of arguments and theorems.
Contrapositive reasoning is particularly useful in mathematics and can be employed to simplify and restate complex statements or to establish the validity of a mathematical proof. It allows for the examination of implications and logical relationships between sets of statements, helping to identify useful information or draw accurate conclusions.

Etymology of CONTRAPOSITIVE
The word "contrapositive" originates from the combination of two Latin terms: "contra" and "positivus".
The term "contra" means "against" or "opposite", and comes from the Latin word "contrā" meaning "against" or "opposite". "Contrā" is further derived from the Proto-Indo-European root *kom, meaning "near or against".
The term "positivus" means "positive" or "placed" and comes from the Latin word "positivus", which is derived from the verb "ponere" meaning "to place" or "to put".
Combined, "contra" and "positivus" form the word "contrapositive", which is used in logic to refer to the opposite or negation of a proposition or statement.
