Sirius 21 Mathematics Vol. 3 Advanced Edition The cover and back cover have some scratches from storage, but the main text is clean with no writing. There are water stains on the lower right approximately 1/6 of the back cover. There are also wrinkles on the pages of the main text, but this does not affect learning. This book can be used as a replacement if your textbook has been water damaged or soiled, or for home study separate from your school textbook.
