Complete seven traceable knowledge objects in dependency order on top of the existing number-system and function foundations.
This is a suggested learning sequence, not a universal logical dependency or a formal proof.

Usual order on the real numbers
The usual real order compares real values and supports finite nonempty extrema, closed intervals, and translation by a common addend.
Quadratic functions in vertex form
A nonzero-coefficient quadratic on all of R has a vertex, an axis of symmetry, and a global minimum or maximum determined by the coefficient sign.
Average rate of change between distinct inputs
Average rate of change is an endpoint difference quotient with a nonzero input difference, not an instantaneous derivative.
Euclidean distance in an equal-unit orthonormal frame
The nonnegative L2 distance in one equal-unit orthonormal coordinate frame is the principal square root of the sum of squared coordinate differences.
Circle boundaries and zero-radius degeneracy
A circle here is the boundary point set at a nonnegative radius from its center, not the filled disk; radius zero yields a singleton.
Exact area of half-open rectangles and unit-cell unions
This entry computes exact area for half-open integer rectangles and finite unit-cell unions, including empty and overlapping cases.
Descriptive summaries of nonempty observation lists
Mean, median, range, and the explicitly defined maximal-frequency set summarize a nonempty finite observation list while retaining multiplicities.
