Mathematics A — Grade 11
A complete English-language course translated and expanded from the Portuguese Domínio — Matemática A, 11.º Ano (Edições ASA). It follows the national Aprendizagens Essenciais for the advanced mathematics track.
Each unit mirrors the textbook's structure: a Recall of prior knowledge, numbered lessons with definitions and formulas, step-by-step worked examples, practice problems with hidden solutions (click to reveal), a summary, and a short final test. Mathematics is typeset with MathJax.
