Within the code, we will often call something like :math:`x^2 + 1` and
*expression* (for example :py:class:`mdpoly.abc.Expr` or
-:py:class:`mdpoly.expressions.poly.PolyRingExpr`) instead of polynomial.

Expressions are more general and can include any mathematical operation. Of
course in the end and expression should result in a polynomial.
