A strong emphasis on the interplay among the various topics serves to reinforce WebIn this section we look at a variation on induction called strong induction. This is really just regular induction except we make a stronger assumption in the induction hypothesis. It is possible that we need to show more than one base case as well, but for the moment we will just look at how and why we may need to change the assumption.

"WebNov 1, 2024 · You can prove it by strong induction on a. For a = 0, it is trivial. Now, consider an arbitrary a ∈ N and assume that each a ′ < a can be written as q b + r, with r < b. Now, if a < b, you can write a as 0 × b + a. Otherwise, consider a − b. By the induction hypothesis, it can be written as b q + r, with r < b. But then a = ( q + 1) b + r.
