Cross-reference with a known index. If the PDF says "Chapter 3 starts on page 98" but a verified table of contents says page 88, you have a bootleg copy of an Applied (workplace) version, not the Principles (academic) version. Official and legitimate ways to access the material

A: Ask the uploader for a screenshot of the Table of Contents page 4, and a random middle page like 230. Compare the formatting to a known good copy from a friend or library. If the uploader refuses, the file is almost certainly corrupted or incomplete.
A: Yes. Principles is the academic, university-preparatory stream (heavy on theory and proof). Foundations is the applied stream (more real-world examples). Ensure your PDF explicitly says "Principles of Mathematics 10" (Academic) and not the "Foundations" version, or you will study the wrong content.
