A dashing, hands-on playground where fundamental math concepts click into place. Drag matrices, roll probabilities, watch calculus unfold — every idea earns its place in your intuition, not just your notebook.
Each topic is a self-guided journey — concepts that build on each other, live widgets you can poke at, and bite-size quizzes that turn curiosity into fluency.
The language of linear systems. Add, multiply, transpose, invert, decompose — every move made visible.
From coin flips to Bayes' theorem. Spin wheels, draw marbles, watch randomness become a tool.
Basics of Descriptive statistics. Build datasets, view central tendencies, dispersion, skewness, and normal curves.
Vectors, spaces, transformations. See the geometry hiding inside every equation.
Limits, derivatives, integrals — built from the ground up with sliders and zoomable curves.
Counting without losing your mind. Permutations, combinations, generating functions, the lot.
The math of change. Phase portraits, slope fields, models that breathe with the parameters.
Concise explanations with real examples. We don't bury the punchline in three paragraphs of throat-clearing.
Every concept ships with a live widget. Drag a slider, change a number, watch the math respond.
Bite-sized checks for understanding. Wrong answers come with hints, not just red marks.
Every term defined, in plain language, with a one-line intuition. Bookmark the ones that bite.
