【Immediate purchase possible】 Negotiations for a price reduction are also possible, though it depends on the circumstances. "Calculus" Ryogo Hirota / Mikio Wadati / Morikazu Toda List price: ¥2700 I used this for about a year and a half at school. I think it's in relatively good condition for a used item, but as shown in the photos, the top part of the cover is slightly wavy and has some fraying. It will be shipped in an envelope after being placed in a plastic bag. #RyogoHirota #Ryogo_Hirota #MikioWadati #Mikio_Wadati #MorikazuToda #Morikazu_Toda #Book #Science/Mathematics
