8.7 Key Points †The. Principle of Mathematical Induction. is stated as follows: Let n be a natural number and let P. n. be a statement that depends on n. If 1. P. 1. is true, and 2. for all positive integers k, P. k+1. can be shown to be true if P. k. is as-sumed to be true, then P. n. is true for all natural numbers n.

The first ordinal number that is not a natural number is expressed as ω; this is also the ordinal number of the set of natural numbers itself. The least ordinal of cardinality ℵ 0 (that is, the initial ordinal of ℵ 0) is ω but many well-ordered sets with cardinal number ℵ 0 have an ordinal number greater than ω.
