WebbThe well-ordering property accounts for most of the facts you find "natural" about the natural numbers. In fact, the principle of induction and the well-ordering property are equivalent. This explains why induction proofs are so common when dealing with the natural numbers — it's baked right into the structure of the natural numbers themselves.

Webbthis thesis we will do an overview of mathematical induction and see how we can use it to prove statements about natural numbers. We will take a look at how it has been used in history and where the name mathematical induction came from. We will also look at di erent types of induction, weak and strong induction.

When n = 0 we nd 10n 1 = 100 1 = 0 and since 9j0 we see the statement holds for n = 0. Now suppose the statement holds for all values of n up to some integer k; we need to show it holds for k + 1. Since 9j(10k 1) we know that 10k 1 ... how are children radicalised

"WebbThe ﬁrst four are fairly simple proofs by induction. The last required realizing that we could easily prove that P(n) ⇒ P(n + 3). We could prove the statement by doing three separate inductions, or we could use the Principle of Strong Induction.
