I'd like to buy 1) The annotated edition of Modern Algebra: A Logical Approach (Allen and Pearson), Book One, 1964 or so. It says "annotated edition" on the cover. and 2) The "teacher's key" for Modern Algebra: A Logical Approach Including Trigonometry, Book Two (Allen and Pearson), 1966 or so. I've been looking for these instructor editions for years. I have a copy of the regular textbooks but without the answers/solutions. The copies listed on the Amazon page aren't usually the Annotated edition despite the photo on the Amazon product page, I asked the sellers.
