"Solutions and Exercises Mathematics 1+A" Chart Research Institute Price: ¥1810 #ChartResearchInstitute #Book #Society/Education/Learning This book was used by a child for learning. There are only a few pages with pencil markings, as shown in the sixth photo. I would like to sell this book to someone who understands that it is a used book that a child has studied. I will send it via Yu-Packet Post, which is a mail slot delivery service. Therefore, as shown in photos 7 to 9, I will detach the answer key and send it separately. Please understand this before purchasing. Although it is a new, unused item, I would like to sell it to someone who understands that it has been in someone's possession once. Please take a moment to read my profile. Thank you."
