mathematical notation
Let an agent explain mathematical notation and its main conventions, relay standards and history from mathematical references, describe regional and field variations such as decimal separators, and distinguish notation from the mathematical concepts it expresses and from typesetting systems.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain mathematical notation and its main conventions, relay standards and history from mathematical references, describe regional and field variations such as decimal separators, and distinguish notation from the mathematical concepts it expresses and from typesetting systems.
The system of symbols and conventions used to write mathematical expressions, including numerals and radix characters such as the decimal point and thousands separators, operator and function notation such as f(x), summation or sigma notation, set, logic and type notations such as type ascription, and diagrammatic systems such as Peirce s existential graphs, developed over centuries and standardised in part by ISO 80000-2; notation varies across countries and fields and shapes how mathematics is taught and communicated.
What it is for: Writing mathematics.
It can be explain conventions; relay standards and history; describe variations; distinguish from concepts and typesetting.
Distinguishing features
Symbolic conventions
Historical layering
Regional variation
Partial standardisation
What it looks like
Symbols, letters and layouts on a page or screen.
Physical character
ISO standard: ISO 80000-2 note - quantities and units, mathematics
decimal separator: point or comma note - varies by country
equals sign introduced: 1557 year - Robert Recorde
How it is recognised
Symbols and conventions for mathematics
Radix characters, thousands separators, function notation, sigma notation, type ascription, existential graphs
The concepts are what notation expresses; LaTeX is a typesetting tool; programming syntax is related but distinct

- How should standards be linked?
- The registry entry has merged aliases naming specific notations; should they be split off?
