    Algebra

    Algebra from arithmetic to university level, split into four courses — Foundations and Expressions, then Equations, Inequalities and Graphs, then Polynomials, Factoring and Quadratics, and finally Functions, Logarithms and Advanced Topics. A hundred and twenty topics and 1,432 problems between them, every one carrying a full worked solution laid out step by step, a hint, and where it fits a four-way multiple choice, all of it machine-checked against a computer algebra system. Nine ways to study: guided learn, practice, quiz, flashcards, a 90-second sprint, a three-lives marathon, mixed exams, a review queue built from what you got wrong, and a plain browse of every example. Take one level at a time, or open the whole subject at once. Every topic is also taught in writing: 120 lectures, one per topic, with worked reasoning, key formulas, defined terms and common pitfalls.

    Algebra 103

    Algebra 103 — Deep Algebra. 36,943 words across 25 lectures, running from polynomial rings and the Factor Theorem to number theory for algebra. Nothing is condensed: every paragraph, sub-heading, table, Spanish example with its English and practice question is stored in reading order and shown in reading order, so what appears on screen is the lecture as it was written rather than a summary of it. The source is native LaTeX, so the mathematics needed no repair at all: every formula is the author's own markup, rendered as written. Twenty-one ways through the same text. Six read it — one lecture entire, an index of every lecture number down the left, a reader that hands you a single section at a time, a continuous scroll, an outline of the section headings, and a syllabus of the whole course. Eight take it apart — every Spanish line beside its English, the glossary lifted out of the tables, the tables on their own, flashcards Spanish side first, the practice questions, a drill that pulls a random example in either direction, and the objectives and closing summaries. Seven keep track — homework, cultural notes, an accent-insensitive search across every block, starred lines, a page of your own notes per lecture, a progress board, and a printable handout. Forty-six colour palettes on a white default with dark one click away, eight colour roles editable by hand, twelve page layouts from a narrow reading column through ruled notebook paper and two magazine columns to a monospaced terminal, seven typefaces with a separate face for the Spanish, and sliders for text size, leading and line length. The English can be hidden to read the Spanish cold, or the Spanish hidden to work back the other way. Progress, stars and notes autosave, with JSON export and import.

    Calculus

    Calculus from the first limit to Noether's theorem, in 108 lectures across twenty-two chapters and five courses. Calculus I opens at limits and continuity and works through the derivative, its applications and the integral; Calculus II covers techniques of integration and their applications, sequences and series, power series, parametric and polar curves; Calculus III moves into space with vectors, partial derivatives, gradients, Lagrange multipliers, double and triple integrals in polar, cylindrical and spherical coordinates, and vector calculus up to Green's, Stokes' and the divergence theorems; Calculus IV is differential equations — first and higher order, Laplace transforms, systems and phase-plane stability, series solutions, Bessel and Legendre functions, Fourier series and the heat, wave and Laplace equations; Calculus V is the capstone — rigorous analysis with epsilon and delta, complex analysis up to the residue theorem, the Gamma function, the Gaussian integral and Stirling's formula, and the calculus of variations from the brachistochrone to Hamilton's principle. Every lecture carries prose sections, a formula list and defined terms, and every one of the 432 worked examples shows each step beside the reason for it, backed by 344 practice questions, 236 quiz questions and 324 unsolved problems to work on your own. Nineteen ways to study: lecture, distraction-free reading, a continuous view that reads the whole course end to end in one scroll, syllabus, formula sheet, cheat sheet and glossary; worked examples, a step-at-a-time reveal, practice and flashcards; quiz, timed mixed exam, drill and random draw; and search, starred items, progress and a printable handout. Thirty-two palettes on a white default with a dark toggle and eight editable colour roles, twelve page layouts, seven typefaces, and sliders for text size, line height, formula size and corner rounding. Formulas are typeset with KaTeX, with a renderer built into the page as a fallback, so there is nothing to install. Progress autosaves, with JSON export and import.

Six read it — one lecture entire, an index of every lecture number down the left, a reader that hands you a single section at a time, a continuous scroll, an outline of the section headings, and a syllabus of the whole course. Eight take it apart — every Spanish line beside its English, the glossary lifted out of the tables, the tables on their own, flashcards Spanish side first, the practice questions, a drill that pulls a random example in either direction, and the objectives and closing summaries. Seven keep track — homework, cultural notes, an accent-insensitive search across every block, starred lines, a page of your own notes per lecture, a progress board, and a printable handout. Forty-six colour palettes on a white default with dark one click away, eight colour roles editable by hand, twelve page layouts from a narrow reading column through ruled notebook paper and two magazine columns to a monospaced terminal, seven typefaces with a separate face for the Spanish, and sliders for text size, leading and line length. The English can be hidden to read the Spanish cold, or the Spanish hidden to work back the other way. Progress, stars and notes autosave, with JSON export and import.
