If your algebra or basic calculus is rusty, start with the introductory appendices. They provide a quick refresher on functions, graphs, and basic rules of differentiation.
Understanding when a unique economic equilibrium exists. If your algebra or basic calculus is rusty,
Economics is often defined as the study of allocating scarce resources to satisfy unlimited wants. Therefore, optimization is the most critical section of the book. Economics is often defined as the study of

Elias sat in the corner of the Regenstein Library, the silence around him heavy and suffocating. Before him lay the object of his obsession and his torment: Mathematics for Economists by Carl P. Simon and Lawrence Blume.
As for the PDF: If you find a clean, searchable version, consider it a rare treasure. But for serious study, invest in the physical book—your eyes (and your understanding of the Implicit Function Theorem) will thank you.
In the landscape of economic education, few bridges between abstract mathematical theory and practical economic application are as well-constructed as Mathematics for Economists by Carl P. Simon and Lawrence Blume. For over three decades, this textbook has served as the canonical gateway for graduate students and advanced undergraduates seeking to move beyond rote memorization toward a genuine fluency in the language of modern economics.
