Topics in Proofs in Mathematics
Mathematical Statements
- A mathematical statement is a sentence that can be judged as either true or false, but not both
- Statements must have unambiguous meaning - everyone should interpret them the same way
- Sentences that are questions, commands, or contain ambiguous terms are NOT mathematical statements
Reasoning in Mathematics
- Deductive reasoning: Drawing logical conclusions from known facts and previously proven statements
- Inductive reasoning: Looking for patterns and making educated guesses (conjectures)
- Mathematical reasoning must be based on logic, not just observation or intuition
Theorems, Conjectures, and Axioms
- Axiom: A mathematical statement accepted as true without proof (self-evident truth)
- Conjecture: A statement believed to be true based on evidence but not yet proven
- Theorem: A mathematical statement that has been logically proven to be true
Mathematical Proofs
- A mathematical proof is a logical sequence of statements that establishes the truth of a theorem
- Each step in a proof must be justified by axioms, previously proven theorems, or logical rules
- Proofs provide certainty - unlike verification with examples, proofs establish truth for ALL cases
