Immediate purchase OK ⭕️ - Title: Linear Algebra - Authors: Toshiharu Nagai, Atsushi Nagai (Co-authored) - List Price: ¥2,420 - Series Name: Mathematics for Science and Engineering Thank you for looking. I purchased this for a class, but I have barely used it and it is in good condition. There were some writings on about 2 pages, but they have been erased. As shown in the photos, there are some creases and wrinkles from being carried in a bag. Please understand.
