Editing Dyadic rational (section)

===In mathematics education===
In theories of childhood development of the concept of a fraction based on the work of [[Jean Piaget]], fractional numbers arising from halving and repeated halving are among the earliest forms of fractions to develop.{{r|hie-ton}} This stage of development of the concept of fractions has been called "algorithmic halving".{{r|pot-saw}} Addition and subtraction of these numbers can be performed in steps that only involve doubling, halving, adding, and subtracting integers. In contrast, addition and subtraction of more general fractions involves integer multiplication and factorization to reach a common denominator. Therefore, dyadic fractions can be easier for students to calculate with than more general fractions.{{r|wells}}
