System Mathematics 2 Algebra Edition 3rd Edition Price: ¥694 This item was used by a child. I don't see any writing inside, but I apologize if I missed anything. There was a name written in it, so I erased it with a marker and covered it with correction tape. Please check the photos. There are no smokers or pets in this household. I am sorry, but I cannot accept price negotiations for single items. I will not respond to comments asking for a price reduction on a single item. I will delete such comments later. I feel uneasy about transactions with those who do not read the product description or profile, so I may block them. If you are interested in multiple items, please leave a comment. #book #nature/mathematics
