Most courses throw you into equations. We start with arrows. Every concept is interactive — drag things around and build the intuition before you touch any formula.

What is a vector? Learn to think geometrically before algebraically.
Matrices aren't grids of numbers — they're instructions for moving space.
Finding where lines (and planes) intersect — geometrically and algebraically.
What does a matrix do to area? The determinant tells you.
The bigger picture: bases, dimensions, and the spaces matrices create.
Some vectors don't change direction under a transformation. Those are special.
Perpendicularity, projections, and how to find the closest point to a line.
Every matrix is a rotation, a stretch, and another rotation. This is SVD.
