I bought the text book "Principles of Corporate Finance" 10th edition, but the page numbers on modules do not match with the book.

For example, in module 1, it says "read chapter 2 of Brealey and Myers, sections 2.1 and 2.2 on pages 20-33". However, section 2.1 starts page 49 for the book I bought. Since I am working out side of the US, I think I recieved Global edition. (It says Global edition on the front cover.)

Does anybody know if there are documents with page numbers of Global edition?
