Observe how every proof begins with an assumption, follows logical reasoning and ends with a justified conclusion.
PROOF / A1–A6
Six structured proof lessons with key ideas, outcomes and worked examples.
Understand how mathematicians construct rigorous proofs using assumptions, logical deductions and conclusions.
A mathematical proof demonstrates that a statement is true for every possible case, not just one example.
Understand assumptions, identify logical deductions and recognise valid mathematical conclusions.
If n is even, write n = 2k. Then n² = 4k² = 2(2k²), so n² is even.
Watch animated lesson →Start with known facts and use valid logical deductions to prove a mathematical statement.
Accepted facts, definitions and algebraic reasoning show that a conclusion must be true.
Identify assumptions, justify each step and state a clear final conclusion.
For consecutive integers n and n + 1, their sum is 2n + 1 and is therefore odd.
Watch animated lesson →Prove a statement by checking every possible case in a finite set.
A proof by exhaustion is valid only when every possible case has been considered.
List cases systematically, verify each one and write a complete conclusion.
For n = 1, 2, 3 or 4, checking n² + n gives 2, 6, 12 and 20—each is even.
Watch animated lesson →Use one valid counterexample to disprove a universal mathematical statement.
A universal statement is false when one case satisfies its conditions but not its conclusion.
Recognise universal statements and verify an appropriate counterexample.
The statement ‘all prime numbers are odd’ is false because 2 is prime and even.
Watch animated lesson →Follow Euclid’s classic proof that there are infinitely many prime numbers.
Assume the opposite and show that the assumption leads to an impossibility.
State the opposite assumption, construct a new number and identify the contradiction.
If p₁…pₙ were all primes, N = p₁p₂…pₙ + 1 has a prime factor absent from the list.
Watch animated lesson →Use contradiction to show that √2 cannot be written as a fraction of integers.
A lowest-terms fraction cannot have both numerator and denominator even.
Assume √2 is rational, manipulate the equation and expose the contradiction.
From √2 = a/b follows a² = 2b², making both a and b even—contradicting lowest terms.
