The math proofs that will be covered in this website fall under the category of basic or introductory proofs. They are considered “basic” because students should be able to understand what the proof is trying to convey, and be able to follow the simple algebraic manipulations or steps involved in the proof itself. The pre-requisite subject of these lessons is Algebra 1.

Proof by Contrapositive ¶ Recall that an implication P → Q P → Q is logically equivalent to its contrapositive ¬Q → ¬P. ¬ Q → ¬ P. There are plenty of examples of statements which are hard to prove directly, but whose contrapositive can easily be proved directly. This is all that proof by contrapositive does. It gives a direct proof of the contrapositive of the implication. This ...
Predicate and propositional logic proofs use a sequence of assertions and inference rules to show logical equivalence or implication.

Mary Radcli e In this set of notes, we explore basic proof techniques, and how they can be understood by a grounding in propositional logic. We will show how to use these proof techniques with simple examples, and demonstrate that they work using truth tables and other logical tools.

Paragraph Proof - Paragraph proofs are logical arguments written in the form of a paragraph, supporting every step with evidences and details to provide a definite conclusion. Two-column Proof - Two-column proof comprises two columns with statements listed in one column while the reasons and logics for each statement stated in the second column.
The Proof Examples collection is a favourite in StudyWell’s collection of downloadable resources (see more downloadable resources). There are 16 exam-style examples in the Mathematical Proof Collection (16 statements to prove or disprove in total) covering proof by deduction, proof by exhaustion and disproof by counterexample.
