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 equations by type, solution method and application, help learners solve them step by step, and avoid personal financial advice when equations model investments.

A mathematical statement that two expressions are equal, usually containing unknowns to be solved for, such as linear, quadratic, polynomial, differential and difference equations, used throughout science, engineering, economics and finance.

What it is for: Modelling relationships and finding unknown values.

It can be classify an equation; solve equations step by step; check solutions; interpret equations in applications.

Distinguishing features

States equality

Has unknowns or parameters

May have none, one or many solutions

Used to model systems

What it looks like

Not physical; expressions with an equals sign.

How it is recognised

An equals sign between expressions

Unknowns such as x or y

Inequalities use signs such as less than
