Summary Title: Understanding Mathematical Proofs

  • A mathematical proof is an inferential argument for a mathematical statement that shows the logical guarantee of the conclusion using axioms and rules of inference.

  • Proofs are examples of exhaustive deductive reasoning and must demonstrate that the statement is true in all possible cases.

  • A proposition that has not been proved but is believed to be true is known as a conjecture or hypothesis.

  • Proofs employ logic expressed in mathematical symbols and natural language which usually admits some ambiguity.

  • The philosophy of mathematics is concerned with the role of language and logic in proofs, and mathematics as a language.

  • The word "proof" comes from the Latin probare (to test).

  • The development of mathematical proof is primarily the product of ancient Greek mathematics, and one of its greatest achievements was the book, the Elements, by Euclid.

  • Further advances also took place in medieval Islamic mathematics.

  • A proof has to meet communal standards of rigor, an argument considered vague or incomplete may be rejected.

  • Methods of proof include direct proof, proof by mathematical induction, proof by contraposition, proof by contradiction, proof by construction, proof by exhaustion, probabilistic proof, combinatorial proof, and nonconstructive proof.

  • A nonconstructive proof establishes that a mathematical object with a certain property exists without explaining how such an object can be found.

  • Understanding mathematical proofs is essential to the field of mathematics and involves rigorous argumentation, formal language, and logical deduction.Mathematical Proof: An Overview
