It is usually useful in … WebFor example, in ordinary induction, we must prove P(3) is true assuming P(2) is true. But in strong induction, we must prove P(3) is true assuming P(1) and P(2) are both true.

To show using strong induction that S(n) is true for all n ≥ 0 we must do this: If we assume that S(m) is true for all 0 ≤ m < k then we can show that S(k) is also true.
