Calculus, linear algebra, and the neuroscience they power. Predict what happens, drag the graph, and prove you understood it.
Predict before calculating. See why each wrong answer fails. Move from visual intuition to AP-style questions.
Mathematics is a language for saying precisely how things change, accumulate, and transform. Theorized teaches that language through instruments rather than lectures: every lesson asks you to predict what a graph will do before you drag it, so understanding gets tested instead of assumed.
The neuroscience chapters are the proof that the language runs on something real. Every neural simulation here is built from the site's own calculus and linear algebra — integrate-and-fire cells, weight matrices, attractors — and every model states plainly what it leaves out.
