Mathematical Proofs

Case Western organizes proof construction around moving between what is known and what must be shown. Definitions, quantifiers and common proof methods lead into uniqueness, induction and maximum or minimum arguments. It suits learners who find finished proofs readable but want a more explicit process for deciding how to begin writing one themselves.

What you will learn

• Interpret definitions and quantified statements.
• Choose direct, contrapositive or contradiction arguments.
• Develop induction and uniqueness proofs.

Who this suits

Intermediate learners seeking a structured approach to proof writing, prepared to check each logical step rather than memorize a finished demonstration.

Before you enroll

Work through examples with a written argument rather than relying on an answer alone. Check definitions, quantifiers and boundary cases, and distinguish a model’s assumptions from the situation it represents. These courses take different routes through discrete mathematics; compare their preparation requirements and topic coverage before choosing a starting point.

Put it into practice

Prove a simple assertion in two different ways. Mark where each argument uses the hypotheses, and explain why the chosen proof method fits the form of the conclusion.
