Official curated learning paths
The rooms that go with the maths labs, from arrows on a grid to how a language model picks its next word. Play a warm-up before its lab, and the rest alongside it.
Froga
An introduction to how compound interest works and why it grows savings and loans faster than simple interest. Good for anyone curious about the maths behind saving, borrowing or investing.

Froga
The handful of ideas Linear algebra 2 builds on: multiplying matching parts, what a right angle means for two arrows, Pythagoras, and why "similar" can mean "pointing the same way". About ten minutes.
Froga
Starts from nothing: directions on a map, arrows you can add and stretch, and rules that move every point at once — which is all a matrix is. About ten minutes.
