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.

Great! We obtained the number divisible by 7, so it means that our original number 13468 is also divisible by 7. Method 2. Take the digits of the number in reverse order. So for our original number 13468, we have 8 6 4 3 1. Multiply them successively by the digits 1, 3, 2, 6, 4, 5. Repeat or shorten this sequence to the necessary length.
