Book of Hard to Solve Mind Puzzles / Math Resource / Education / School

Book of Hard to Solve Mind Puzzles / Math Resource / Education / School This is a used book. It may have signs of wear such as corner folds, marks, highlighting, inscriptions, etc. I tried to take photos of any issues I saw but I did not examine every page. 😉 Books are weighty items (in more ways than one). Please reach out to me before making a large bundle with books as 5kg is the limit with Poshmark. Please view all photos and zoom for greater detail. Thanks for stopping by. 😊
