In mathematics, we use a form of complete induction called `color{green}ul "mathematical induction."`
`\color{green} ✍️` To understand the basic principles of mathematical induction, suppose a set of thin rectangular tiles are placed on one end, as shown in Fig.
When the first tile is pushed in the indicated direction, all the tiles will fall. To be absolutely sure that all the tiles will fall, it is sufficient to know that
`(a)` The first tile falls, and
`(b)` In the event that any tile falls its successor necessarily falls.
`\color{green} ✍️` This is the underlying principle of mathematical induction. We know, the set of natural numbers `N` is a special ordered subset of the real numbers. In fact, `N` is the smallest subset of `R` with the following property:
A set `S` is said to be an inductive set if `1∈ S` and `x + 1 ∈ S` whenever `x ∈ S.` Since `N` is the smallest subset of `R` which is an inductive set, it follows that any subset of `R` that is an inductive set must contain `N.`
