The previous owner wrote in the problem set and Toretore, so they show signs of use. I have erased most of the writing in the Toretore for use, but the problem set remains as is because I did not use it. Also, due to the major legal revisions in 2025, I have rewritten parts of the explanations in the textbooks and problem sets to reflect the revisions. Thank you for your consideration.
