Let an agent explain concrete numbers, relay the distinction from abstract numbers in mathematics education and philosophy from mathematics sources, describe the named number-based concepts and flag them as misfiled, and distinguish concrete numbers from quantities with units, cardinal numbers, collective nouns and the named things themselves.

What it is Filled

A number used together with a named unit or collection of objects, such as three apples or five kilograms, as opposed to an abstract number, and in the registry a class grouping named sets of a specific count; its aliases, however, name things defined by a number rather than numbers themselves, such as tricameral and pentacameral legislatures with three and five chambers, the Japanese hyakushu uta, a sequence of one hundred poems, medical triads of three clinical signs, and terms for groups of nineteen and twenty, enneadecad and icosad, which are better linked to their own subjects.

Why it exists Filled

Let an agent explain concrete numbers, relay the distinction from abstract numbers in mathematics education and philosophy from mathematics sources, describe the named number-based concepts and flag them as misfiled, and distinguish concrete numbers from quantities with units, cardinal numbers, collective nouns and the named things themselves.

Distinguishing features Filled

  • Tied to units or objects
  • Educational concept
  • Contrasts with abstract numbers
  • Aliases are misfiled

What robots and AI may and may not do Filled

Must not

  • Drop the unit from a concrete number in a way that changes its meaning.
  • Add or compare concrete numbers with different units without conversion.
  • Present a count of people or items more precisely than the source supports.

Only with a human decision

  • Publishing counts that drive decisions on resources for people.

May

  • Distinguish concrete numbers, tied to units or objects, from abstract numbers in teaching and data.
  • Check that quantities in a calculation carry their units consistently.

Moral aspects Filled

  • Counts of people and goods guide policy; careless numbers mislead.

Who is affected

  • Students
  • Users of statistics

Owners Filled

Steward

Nobody owns the concept.

Links to other meta-models Filled

parent

  • Q107715 - registry parent class

related

  • physical quantity - in registry terms
  • abstract number
  • cardinal number
  • tricameralism - misfiled alias

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.concrete-number
  • Wikidata: Q4025884 (https://www.wikidata.org/wiki/Q4025884)

Direct properties not applicable Not applicable

  • example: 3 apples note
  • hyakushu: one hundred poems note - as in Hyakunin Isshu
  • registry parent: physical quantity note

Plane XCT: no invented physical properties.

Recognition optional Filled

  • Number attached to a unit or collection
  • Tricameral legislature, pentacameral legislature, hyakushu uta, medical triad, enneadecad, icosad
  • Quantities combine numbers and units; cardinals are abstract sizes; collective nouns name groups; legislatures and poems are things
  • Not a visible object; expressions such as three books.

Capabilities and actions required Filled

  • explain the concept
  • relay the abstract versus concrete distinction
  • describe named number-based concepts
  • flag misfiled aliases

Hazards and failure modes required Filled

  • Treating named groups as numbers
  • Confusing counts and measurements
  • Misfiled aliases

Standards and interfaces required Filled

  • ISO 80000-1 on quantities and units

Context of use required Filled

  • Counting and measuring specific things.
  • counts of objects
  • measurements with units
  • number-named groups such as triads
  • number-based institutional forms such as tricameralism

Sources Filled

  1. Wikidata item Q4025884: concrete number - identity and sense of the item
  2. Wikipedia: Concrete number - general description of the item

Open questions

  • The registry aliases naming legislatures, poem sequences and triads should be moved to their own entries
  • How should mathematics education sources be linked?
  • Should concrete number be merged with quantity entries?
