"Ogino's Math III & C to Raise Heroes vol. 1" by Nobuya Ogino This is an old reference book. I think it's easy to read. If you're interested, please take a look. It's quite old, so there's some soiling. There were some marks on the questions, but I erased them with an eraser as much as I noticed! There might be some I missed, but Please refer to the photos. Please purchase with an understanding of used books. There are no smokers or pets. Please refrain from purchasing if you are overly concerned about the condition, as it is a used item. Thank you. #NobuyaOgino #Books #Mathematics #RaisingHeroes #Yozemi #YoyogiLibrary
