Choose a tool

Learn span and linear maps
by playing with them.

Two focused tools, built for intuition first: drag vectors, see geometry, then connect it back to the formal definitions.

I’m adding small, high-signal modules (no clutter) as I build them.

Eigenvectors

Determinants

Rank & Nullity

SVD

Minimal UI, math-forward typography, and “see it happen” interactions.

Intuition → Formalism Start with geometry and examples. Then translate what you saw into definitions and proofs.

Student-friendly defaults Small inputs, readable labels, and smooth interactions — not a million buttons.

Built to be extended Each tool is a separate page, so adding new modules is just adding a folder.
