ANIMATED LESSON

Structure of
mathematical proof.

Observe how every proof begins with an assumption, follows logical reasoning and ends with a justified conclusion.

PROOF / A1–A6

Reason it.
Prove it.

Six structured proof lessons with key ideas, outcomes and worked examples.

A1 · 12 minutesStructure of Mathematical Proof+

Understand how mathematicians construct rigorous proofs using assumptions, logical deductions and conclusions.

Key idea

A mathematical proof demonstrates that a statement is true for every possible case, not just one example.

Learning outcome

Understand assumptions, identify logical deductions and recognise valid mathematical conclusions.

Worked example

If n is even, write n = 2k. Then n² = 4k² = 2(2k²), so n² is even.

A2 · 12 minutesProof by Deduction+

Start with known facts and use valid logical deductions to prove a mathematical statement.

Key idea

Accepted facts, definitions and algebraic reasoning show that a conclusion must be true.

Learning outcome

Identify assumptions, justify each step and state a clear final conclusion.

Worked example

For consecutive integers n and n + 1, their sum is 2n + 1 and is therefore odd.

A3 · 12 minutesProof by Exhaustion+

Prove a statement by checking every possible case in a finite set.

Key idea

A proof by exhaustion is valid only when every possible case has been considered.

Learning outcome

List cases systematically, verify each one and write a complete conclusion.

Worked example

For n = 1, 2, 3 or 4, checking n² + n gives 2, 6, 12 and 20—each is even.

A4 · 11 minutesDisproof by Counterexample+

Use one valid counterexample to disprove a universal mathematical statement.

Key idea

A universal statement is false when one case satisfies its conditions but not its conclusion.

Learning outcome

Recognise universal statements and verify an appropriate counterexample.

Worked example

The statement ‘all prime numbers are odd’ is false because 2 is prime and even.

A5 · 14 minutesProof by Contradiction: Infinite Primes+

Follow Euclid’s classic proof that there are infinitely many prime numbers.

Key idea

Assume the opposite and show that the assumption leads to an impossibility.

Learning outcome

State the opposite assumption, construct a new number and identify the contradiction.

Worked example

If p₁…pₙ were all primes, N = p₁p₂…pₙ + 1 has a prime factor absent from the list.

A6 · 14 minutesThe Irrationality of √2+

Use contradiction to show that √2 cannot be written as a fraction of integers.

Key idea

A lowest-terms fraction cannot have both numerator and denominator even.

Learning outcome

Assume √2 is rational, manipulate the equation and expose the contradiction.

Worked example

From √2 = a/b follows a² = 2b², making both a and b even—contradicting lowest terms.
