Values are exact mathematical quantities. The 3D depth, marker size, and hopping motion are visual aids, not extra dimensions of the number line.

No focus. Tap a marker, zero, a unit interval, or a connecting arrow.

Zoom1×

Drag empty space to pan. Scroll or pinch to zoom. Focus follows the selected object without changing its numerical position.
