degree of a polynomial
Let an agent explain the degree of a polynomial and its properties, support finding degrees and using them in algebra, describe the role of degree in roots and graphs, and support learning.
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 the degree of a polynomial and its properties, support finding degrees and using them in algebra, describe the role of degree in roots and graphs, and support learning.
The highest power of the variable with a non-zero coefficient in a polynomial, or for polynomials in several variables the largest total degree of any term, a non-negative integer that determines the number of roots over the complex numbers, the shape of the graph, and the behaviour under operations such as addition, multiplication and differentiation; the degree of a polynomial is fundamental in algebra and is used to classify polynomials as constant, linear, quadratic, cubic and higher.
What it is for: Highest power in a polynomial.
It can be explain the concept; support finding degrees; describe role in roots and graphs; support learning.
Distinguishing features
Non-negative integer
Determines root count
Behaves under operations
Classifies polynomials
What it looks like
Not physical; a number attached to an expression.
How it is recognised
Highest exponent with non-zero coefficient
Non-negative integer
The order of a differential equation is a different notion; leading coefficient is the coefficient of the top term
