Web2.1 Mathematical induction You have probably seen proofs by induction over the natural numbers, called mathematicalinduction. In such proofs, we typically want to prove that some property Pholds for all natural numbers, that is, 8n2N:P(n). A proof by induction works by ﬁrst proving that P(0) holds, and then proving for all m2N, if P(m) then P ... WebMathematical induction is a proof method often used to prove statements about integers. We’ll use the notation P ( n ), where n ≥ 0, to denote such a statement. To prove P ( n) with induction is a two-step procedure. Base case: Show that P (0) is true. Inductive step: Show that P ( k) is true if P ( i) is true for all i < k.
