Ana was staring at the ceiling of her small apartment, feeling defeated. At 24, she had just enrolled in a technical course in logistics. She could manage the concepts of supply chains and inventory, but there was one massive problem: the math.

The results flooded in. Free PDFs from universities, curated exercise lists from tutoring blogs, and even old textbooks from Brazilian public schools. She clicked on the first link—a clean, 50-page PDF titled "Caderno de Exercícios: Matemática para Começar" (Exercise Notebook: Math to Start With).
