Mathematica: A Practical Approach by Nancy Blachman, translated by Susumu Sakakibara Prentice Hall Toppan Price: 3800 yen + tax First Edition: July 10, 1992 Fourth Printing: July 5, 1994 This book was read by my family. I am decluttering. It has been on the bookshelf for a long time. I haven't opened it much, but there is some yellowing due to age. The inside can be read without any problems. There are three places with writing (name stamp, purchase date). Please be aware of this. It is heavy and thick, so it will be shipped via Yu-Packet Post.
