binary operation
Let an agent handle binary operations by definition, properties, examples and role in algebraic structures.
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 handle binary operations by definition, properties, examples and role in algebraic structures.
An operation that combines two elements of a set to produce an element, such as addition, multiplication, composition of functions or the Poisson bracket; properties include associativity, commutativity, identity and inverses.
What it is for: Defining algebraic structures such as groups, rings and fields.
It can be check properties of an operation; give examples and counterexamples; identify algebraic structures; use operation tables.
