Regarding the Try & Try Mathematics word problems, as shown on the third page of the photo, there were writings on the first two pages only, so the pencil markings have been erased with an eraser. I believe there are no other writings. I apologize if I missed anything. Regarding Juku Waza 100 Mathematics, as shown on the fourth page of the photo, it has been used up to item 8 and has writings. There are no writings on the other pages, but there are some parts highlighted with a marker. I purchased these books new and used them for entrance exams, but I didn't use them all and they have been stored at home. There are no pets or smoking in the house. Please consider purchasing these books, taking into account that they have been stored at home. Please feel free to purchase them.
