Rational Number

Any number that can be expressed as a quotient of two integers. For example, one-tenth is a rational number because it can be expressed as 1/10.

It is possible to suppose that the discreteness of normal distributions (and, as is obvious, any other distributions as well) is their core property originated from that the rational numbers are distributed with different density along the axis of numbers [2,3].
The notion of fraction is introduced in the context of halving and repeated halving and then extended at other levels to include: unit fractions, readily-visualised fractions, equivalent fractions, rational numbers, real numbers and the algebraic fractions at the highest level.
In what follows, the focus will be on fractions specifically, although the research is often framed in terms of rational numbers.
Working from the conviction that anyone with a high school education should be able to work through his self-contained chapters (although having a basic background in calculus would help), Goodfriend describes logic and techniques for proofs, elementary set theory, development of integers, their properties and application, fields and the rational numbers, the development of real numbers.
