2. Deductive reasoning

  • Deductive reasoning starts from given premises or hypotheses and draws a logical conclusion.
  • The truth of the conclusion depends on the truth of the hypotheses.
  • A proof uses valid arguments in a correct sequence.

3. Conjectures and counter-examples

  • A conjecture is an intelligent guess based on patterns.
  • Checking many cases does not prove a conjecture true for all cases.
  • A single counter-example is enough to disprove a statement.

4. Direct proof and proof by exhaustion

  • A direct or deductive proof begins from given facts and reaches the conclusion step by step.
  • The sum of two rational numbers is rational.
  • If x = m/n and y = p/q, then x + y = (mq + np)/nq, which is rational because the numerator and denominator are integers and nq ≠ 0.
