"World Mathematical Olympiad" Tetsuya Ando Price: ¥1900 #TetsuyaAndo #Tetsuya_Ando #Book #Nature/Mathematics This product is a "cut" product. (The pages are separated one by one) Therefore, the condition of the product is listed as "Has scratches and stains." Please be careful not to make a mistake. There is no cutting of text or figures due to the cutting process. As far as I can see, there are no writings, but please forgive me if I missed something. At least, there are no noticeable writings on many pages.
